DUCTILITY

Although the interstory drift ratio is used as a limiting factor for specific performance levels by the structural engineering profession, its distribution among the stories is generally disregarded. Observations and analytical studies have shown that even the structures are des…

The concept of stay-in-place (SIP) structural formwork has the potential to simplify and accelerate the construction process to a great extent. Fibre-reinforced polymer (FRP) SIP structural formwork offers further potential benefits over existing formwork systems in terms of eas…

In tall single-storey steel structures such as sports facilities, airplane hangars, industrial buildings or warehouses, multi-tiered concentrically braced frames (MT-CBFs) are commonly used. MT-CBFs consist of a bracing system where multiple braced panels are stacked over each o…

Performance-Based Design (PBD) has gained popularity as a procedure for the seismic design of structures. In order to achieve the objectives of PBD, it is essential to have accurate modelling approaches. Non-linear Time History Analysis (NLTHA) is the most complex technique that…

The reinforcement detailing of reinforced concrete frame and wall-frame structures, in regions where the probability of a seismic event is not significant, is characterized by lack of special consideration for meeting ductile response requirements. The buildings are normally des…

This research is concerned with the assessment of seismic demand parameters that are needed to implement a capacity/demand based seismic design approach. The objectives of the study are (a) to assess the importance of different demand parameters, (b) to evaluate patterns in dema…
