Research Interests

I have a passionate interest to research on structural and computational mechanics, with specific application to steel, concrete and composite structures subjected to extreme actions including fire, blast, impact, earthquake and tsunami.  I lead a research group to develop original two-phase experimental methods to investigate the effect of multi-phase loading scenarios on construction materials as the current codes of practice have been proven inadequate to address the combined effect of extreme events. My group is also the first to develop a fabricated corrugated section to facilitate the use of ultra-high strength steel (UHSS) in civil engineering construction. UHSS tubes are used mainly in the automotive industry, but their available size is too small for civil infrastructure applications. The outcomes of this research overcome the bottleneck and open a new market for UHSS in civil construction. The new sections are lighter, stronger and more affordable.

Through collaboration with Australian industry and international eminent research institutions, we research on new emerging biotechnology for self-healing of concrete to make our infrastructure more resilient in extreme events. The outcome of this research has the potential to lead to a reduction in the amount of repairs needed for concrete infrastructure. The benefits could include safer concrete infrastructure, significant maintenance cost savings and lead to a lower carbon footprint in construction.

Research Projects

Current projects

Innovative beam to hybrid fabricated column connections

The conventional types of connections (flush and extended end plate connections, reverse channel and ConXL connections) have been proven to be not suitable to be used with the hybrid fabricated columns recently developed at Monash University.  Therefore, a new modular connection has been designed to maximise the benefit of materials such that the significant portion of the load is transferred from the beam to the high strength tubes at the corner of the column whilst the rotation capacity is controlled by the ductile mild-steel plates and additional components. Extensive experimental tests and numerical models have been developed to demonstrate the capability of this patented connection.  Moreover, a robust component-based model is being developed to accurately capture the behaviour of the proposed connection under monotonic loading.

Behaviour of ultra-high strength steel (UHSS) under cooling phase of a fire

During a fire hazard, if only partial damage or no damage occurs in the structure, it might be possible to reuse the structural member. However, after a structure is cooled down from a fire temperature, residual stresses might be developed. In order to conduct a rational thermal analysis in which the effect of residual stresses are taken into account, investigating the mechanical properties of the materials under cooling phase of fire is essential. In this study, the mechanical properties of ultra-high strength steel (UHSS) tubes under fire and after cooling from fire temperatures of up to 800ºC, are studied experimentally. The effects of cooling rate and the creep of the material during fire are also investigated. Micro-structure examination on UHSS material is conducted using optical and scanning electron microscopy (SEM) methods which will be used to interpret the experimental results. In order to consider fire hazards in extreme cold conditions, the mechanical behaviour of test specimens cooled to sub-zero temperatures, are also investigated.

Moreover, based on the results obtained from experimental tests, a material constitutive model which take into account the post-fire behaviour of UHSS material is developed. The constitutive model can be implemented into commercial finite element packages such as ANSYS and ABAQUS to carry out a rational thermal analysis and perform fire safety design.

 

Concrete filled double skin tubular members consisting of corrugated plates and ultra-high strength steel tubes

Concrete-Filled Double-Skin Tubular (CFDST) sections are consisting of two hollow steel skins while the gap between the two skins is filled with concrete. Since CFDST sections use the merits of high compression strength of the concrete core as well as the ductility of the steel material as the surrounding skins, these sections were introduced as an appropriate choice in structural design. The current research would mainly focus on the behaviour of another innovative section type for the Concrete-Filled Double-Skin Tubular (CFDST) sections. The intended sections in this study take the advantage of corrugated plates as the steel skins and ultra-high strength (UHS) steel tubes at the corners. Hence, inner, outer or both skins of these columns are built up from the corrugated plates. In order to investigate the behaviour of these columns and the effect of substituting ordinary flat mild-steel plates in CFDST sections with corrugated ones, comprehensive experimental and numerical studies are conducted.

 

Effect of strain ageing on mechanical properties of steel and concrete under multi-phase loading

The behaviour of structural materials including steel and concrete under extreme loading conditions is a key element in retrofitting of partially-damaged structures. Mechanical properties of construction materials can substantially change by time effects, which is the main focus of this research work. The strain ageing effect on partially damaged structures has not been incorporated in civil engineering design guidelines. As a result, analysis and design of structures based on the existing constitutive material models without considering the strain ageing effect may not be accurate.

In this research, the strain ageing effect on the mechanical properties of structural steel partially-damaged by individual effect or combined actions of quasi-static, cyclic or high strain rate loading and thermal loading is investigated. Moreover, the effect of strain ageing on concrete partially damaged by quasi-static loading is comprehensively studied. The original experimental results reported in this research work can be used to develop constitutive material models incorporating the strain ageing effect for the prescriptive codes of practice and finite element method (FEM) based software packages, such as ABAQUS and LS DYNA, where rational structural analysis and design are required.

Hybrid high strength fabricated steel sections

With the ever‐increasing application of high strength steel material in industries due to their unique characteristics such as strength, energy absorption, weight and cost saving, there is a high potentiality for taking advantage of the exceptional capacities of this material in construction practice. Steel materials with yield strengths higher than 700MPa are quite rarely used as the main construction material in civil structures and are lacking from available design standards. This research investigates an innovative application for high and ultra‐high strength steel tubes in hybrid fabricated sections taking advantage of the combined material properties of the constituting elements under monotonic and cyclic loading states in terms of strength, local buckling behaviour and ductility.

Monotonic and seismic experimental results obtained in this research can be incorporated in the development of reliable nonlinear analysis models of frames consisting of these sections for damage and collapse simulation of structures.

 

Resilient hollow hybrid corrugated members

In today’s world, organised research and development have greatly increased the production of new knowledge. Over the past few decades, innovations and the outcome of innovative activities have surrounded us; some affect our life more than others while some are more noticeable than others. Indeed, technology evolution gradually forms our modern life. On this journey, structural engineers are not an exemption though. They have always been trying to find more resilient structural members in order to build high performance infrastructure. As an attempt to achieve this goal, innovative Hybrid Corrugated (HC) sections are introduced and examined in this research.

The HC sections exhibit superior behaviour in comparison to conventional tubular sections, not only on the performance of structures, but also from an aesthetic point of view. The square shape of these hollow sections are comprised of four corrugated plates which may or may not have corner tubes welded to the apexes of the section. The material of plates is from medium strength structural steel whilst it is ultra-high strength steel for the corner tubes.

The results of this research will help engineers to compare the superior performance of HC sections with equivalent fabricated sections and tailor HC sections according to their needs and reach to an optimised configuration. The derived analytical formulation has the potential to be used in the codes of practice for rational analysis and design of HC sections.

Post-impact/blast fire behavior of construction materials

In today’s world, designing structures to withstand normal lading conditions is not safe enough and engineers aspire to design protective structures that can withstand extreme loading scenarios. With the unfortunate rise of terrorist attacks and road side accidents causing explosions or high speed collisions, survivability of structures under large dynamic loads and potential subsequent fire initiating from them have become a major design concern for structural engineers. The post-impact/blast fire combined effect is profoundly different from when the structure is exposed to either loading. That is, the subsequent fire is imposed on a structure which is now in an altered and potentially weaker state to what had been assumed during the original fire-resistance design. Finite element method based software packages currently used in engineering practice for structural analysis rely on constitutive models to predict material response and simulate deformations. Accurate material models that can predict the behaviour of structural materials under such extreme loading conditions are essential for analysis and design of structural systems.

This research has developed a fundamental understanding of the behaviour of conventional construction materials namely steel, concrete and steel-concrete composites under the combined actions of post-impact-fire and to present material models which can accurately reflect such complex behaviours.

Performance of cyclically-damaged material at elevated temperatures

Current design guidelines allow structures to dissipate seismic energy through plastic deformations. As a result, a fire following an earthquake would find a structure in a weaker state than what had been originally assumed during its fire-resistant design. This research aims to investigate the potential changes that the mechanical properties of construction materials experience under earthquake-then-fire loading sequence.

The results of this research indicate that a prior history of cyclic loading can significantly affect the ductility and strength of steel and concrete at elevated temperatures. These variations in material properties have great implications when it comes to post-earthquake fire analyses, suggesting that any history of cyclic loading should be included in the post-earthquake fire-resistant design of a structure. Therefore, it is desirable to establish a relationship for each mechanical property, not only as a function of temperature but also the level of damage induced by cyclic loading. Moreover, the results of this research can be used to develop fire-resistant guidelines for structures located in earthquake-prone areas.
