Abstract In this study, the response of ten composite post-tensioned concrete beams topped by a reinforced deck with adequate reinforcing shear connectors is investigated. Depending on compressive strength slab (20, 30, and 40 MPa), are grouped into three categories. Seven these exposed to fire attack 700 800 °C temperature simultaneously or without presence uniformly distributed sustained stat...

Prefabricated beam–column connections are the most vulnerable components of prefabricated buildings during earthquake events. The seismic performance connection is functional as critical component plays a key role in structural safety. This study aimed to develop novel hybrid concrete (HPC) connection, combining with wet and dry techniques, enhance frames. A quasi-static experimental investigat...

The development of strong and stiff lateral load-resisting systems (LLRS) is essential for mid-rise high-rise timber buildings. On the other hand, within a seismic design philosophy, strength/stiffness ductility/drift capacity typically appear as opposite target parameters, depending on acceptable level damage. For improved stiffness strength, core-wall tubular structural forms commonly are use...

Abstract Post-tensioned precast concrete walls are an attractive research trend in structural engineering, which replaces cast-in-place earthquake-prone buildings. Precast use mild steel and high-strength post-tensioning for flexural resistance. Mild reinforcement yields tension compression, dissipating inelastic energy. Unbounded tendons used inside the wall to give self-centering capability, ...
