The response of a steel moment resisting frame (MRF) depends on the specifications of its main components, namely the columns, beams and connections. One important connection element which can significantly affect frame behavior is the panel zone (PZ). The PZ is described to be an element mainly subjected to shear stresses and its failure mode is often governed by shear yielding. Several analyt...

Past earthquakes have highlighted the seismic vulnerability of prefabricated industrial sheds typical past Italian building practices. Such buildings typically exhibited rigid collapse mechanisms due to absence links between columns, beams, and roof elements. This study aims at presenting experimental numerical assessment a novel dissipative connection system (DCS) designed improve performance ...

Michael G. Oliva, Ph.D. Professor Department of Civil and Environmental Engineering University of Wisconsin–Madison Madison, Wisconsin The in-plane fl exibility of untopped precast concrete double-tee diaphragms is often ignored in current design practice. The performance of parking structures during earthquakes and subsequent research studies have shown, however, that in-plane fl exibility of ...

Beam-to-column joints are one of the most common types in metal structures. In design load-bearing aluminium structures, welding, as a joining method, is often avoided because localised degradation mechanical properties heat-affected zone (HAZ). However, recent experimental studies on extent and strength HAZ show significant difference compared to very conservative rules when modern welding tec...

The effects of Dextra Groutec couplers on the global performance precast reinforced concrete frames are investigated by comparing criteria conventional RC structures to that said such elements connected end-to-end using these couplers. As provide continuity reinforcement, this mechanism can perform as a unit, and entire structural system be considered emulative long is comparable conventionally...
