Research is conducted into the design and analysis of structures that includes consideration of the effects of dynamic loading, blasting and fire. Our group continues to investigate alternative aspects of designing and assessing structures using up-to-date research including dynamic analysis techniques, simulated blasting techniques and fire modelling.
We also undertake structural health monitoring to assess structures that are already in-service. Structural Mechanics is a strong stream in the Civil, Architectural and Mechanical Engineering programs taught by our research members. Related units include solid mechanics, structural design, stress analysis and structural dynamics.
Our collaborative projects on fire in structures, and on aspects of sustainable buildings have been mutually beneficial.

Fadillawaty Saleh PhD Structural damage detection in reinforced concrete beams under dynamics vibration. Indunil R. Seven large-scale RC rectangular hollow column specimens were tested under monotonic or cyclic lateral loads.
The most important design parameter was column length-to-depth aspect ratio ranging between 1.
Also, several pioneering shear models proposed around the world, all of which were mainly based on tests for columns with solid sections, were reviewed and compared with the test results of this study, for their possible applications to columns with hollow sections. After all, an empirical equation was proposed for concrete contribution to the initial shear strength of RC hollow columns based on fundamental mechanics and the test results.
Differential quadrature method for free vibration analysis of coupled shear walls K. Bozdogan Abstract; Full Text K. Abstract Differential Quadrature Method DQM is a powerful method which can be used to solve numerical problems in the analysis of structural and dynamical systems. In this study the governing equation which represents the free vibration of coupled shear walls is solved using the DQM method.
A one-dimensional model has been used in this study. At the end of study various examples are presented to verify the accuracy of the method. Key Words differential quadrature method; coupled shear wall; free vibration; continuum model; sandwich beam Address K. Assessment of a concrete arch bridge using static and dynamic load tests B. Abstract Assessment of a monumental concrete arch bridge with a total length of meters having three major spans of 30 meters and a height of 65 meters, which is located in an earthquake-prone region in southern part of the country is presented in this study.
Three-dimensional finite element model of the bridge was generated using a commercially available general finite element analysis software and based on the outcomes of a series of in-depth acceleration measurements that were conducted on-site, the model was refined. By using the structural parameters obtained from the dynamic and the static tests, calibrated model of the bridge structure was obtained and this model was used for necessary calculations regarding structural assessment and evaluation.
Key Words concrete arch bridge; dynamic test; model calibration; impact factor; rating factor Address B. Based on the test results and shear failure characteristics, the shear force hysteretic curves and displacement envelope curves of the models were obtained and discussed. On the basis of the hysteretic curves a general skeleton curve of the shear force and displacement was formed.
The deformation capacity of the specimens was discussed, and the formulas for calculating the lateral stiffness of the walls at different loading stages were proposed as well. This value illustrates that if the walls are appropriately designed, it can fully meet the seismic requirement of the structures. The quadri-linear restoring models of the walls degradation by the test results accurately reflect the hysteretic behaviors and skeleton curves of the masonry walls.
Dynamic analysis of frames with viscoelastic dampers: a comparison of damper models R. Lewandowski, A. Bartkowiak and H. Maciejewski Abstract; Full Text K. Abstract Frame structures with viscoelastic VE dampers mounted on them are considered in this paper. It is the aim of this paper to compare the dynamic characteristics of frame structures with VE dampers when the dampers are modelled by means of different models. The classical rheological models, the model with the fractional order derivative, and the complex modulus model are used. A relatively large structure with VE dampers is considered in order to make the results of comparison more representative.
The formulae for dissipation energy are derived. The finite element method is used to derive the equations of motion of the structure with dampers and such equations are written in terms of both physical and state-space variables. The solution to motion equations in the frequency domain is given and the dynamic properties of the structure with VE dampers are determined as a solution to the appropriately defined eigenvalue problem. Several conclusions concerning the applicability of a family of models of VE dampers are formulated on the basis of results of an extensive numerical analysis.

Time-dependent effects on dynamic properties of cable-stayed bridges Francis T. Au and X. Si Abstract; Full Text K. Abstract Structural health monitoring systems are often installed on bridges to provide assessments of the need for structural maintenance and repair. Damage or deterioration may be detected by observation of changes in bridge characteristics evaluated from measured structural responses. However, construction materials such as concrete and steel cables exhibit certain time-dependent behaviour, which also results in changes in structural characteristics.
If these are not accounted for properly, false alarms may arise. This paper proposes a systematic and efficient method to study the time-dependent effects on the dynamic properties of cable-stayed bridges. After establishing the finite element model of a cable-stayed bridge taking into account geometric nonlinearities and time-dependent behaviour, long-term time-dependent analysis is carried out by time integration. Then the dynamic properties of the bridge after a certain period can be obtained. The effects of time-dependent behaviour of construction materials on the dynamic properties of typical cable-stayed bridges are investigated in detail.
