Seismic analysis and design of a precast concrete framed

Seismic analysis and design of a precast concrete framed structure Precast concrete and particularly pre-stressed precast concrete structures have a poor reputation for seismic response. This can be mainly attributed rather to the behave as diaphragms. In addition to the precast columns, the lateral force

As it has been learned from recent earthquakes, reinforced concrete buildings have historically been designed and constructed in ways that jeopardize their seismic performance. In particular, the early use of Precast Pre-stressed Hollow-Core (PPHC) floors saw the use of support connections that are susceptible to undesirable failure modes when
