This paper attempts to improve the computational efficiency of the well known particle swarm optimization (PSO) algorithm for tackling discrete sizing optimization problems of steel frame structures. It is generally known that, in structural design optimization applications, PSO entails enormously time-consuming structural analyses to locate an optimum solution. Hence, in the present study it i...

Wire arc additive manufacturing (WAAM) is a method of metal three-dimensional (3D) printing that has the potential for significant impact on construction industry due to its ability produce large parts with reasonable times and costs. However, there currently lack fundamental data performance structural elements produced using this manufacturing. Seeking bridge gap, compressive behavior resista...

Steel frame with steel plate shear walls (SPSWs) is used to resist lateral loads caused by wind and earthquakes in high-rise buildings. In this load-resisting system, the cost performance are more efficient than moment system. Behaviors of beam-to-column connections assumed be pinned or fixed simplify calculation past few decades. However, studies have stated that such a simulation fails reveal...

Vibration serviceability of staircases is an increasing challenge due to evolving materials and structural forms. To predict the dynamic performance staircases, accurate models are required. However, few technical guides available for designing steel those that exist often limited in their applications a lack research. This research aimed improve understanding accuracy global vibration response...
