Advanced Steel-Timber Self-Centering System for Seismic Applications

Ahmed Mowafy (Ph.D.)

Ahmed’s research goal is to study and evaluate the seismic response of an advanced steel-timber hybrid system. Generally, advanced structures that combine ductile and recyclable materials offer a viable sustainable solution to resist lateral and gravity loads. An example of this kind of sustainable system is steel-timber hybrid structures, where the steel frame acts as a lateral load resisting system and the timber frame carries gravity loads. There are several benefits of using timber such as structural efficiency and clean environmental usage, by using steel it overcomes brittle failure manner of timber that lacks the capacity to absorb seismic-input. The main challenge in this system is how to develop beam-column connections with seismic dissipation capability between the steel and the timber part without having any local failure in the timber itself.  Therefore, the design concepts of this system will be examined through numerical modelling and physical experiments. The primary research goal is to better understand the behaviour of the proposed hybrid steel–timber system in seismic applications and propose seismic design procedure for this system.
