Seismic behavior of full-scale wall piers with high-strength steel reinforcement

The introduction of openings in structural walls could cause unfavourable seismic behaviour, leading to stringent reinforcement requirements for wall piers. High-strength steel with a reduced amount of reinforcement has the potential to relieve reinforcement congestion. However, the effect of the reduced areas of high-strength steel on the seismic performance of wall piers remains largely unknown, impeding its application in earthquake-prone …
