摘　　要：大量试验及事实表明,地震对建筑物的破坏大多集中在柱梁节点处。为确保柱梁节点处的抗震效果,在保证"强柱弱梁"基本理念的同时,尝试采用在核心区加设型钢芯柱代替核心区高强度混凝土,减少核心区钢筋密度,提高柱梁节点抗震性能,从而真正实现"强柱弱梁"。A large number of tests and facts show that the damage of buildings caused by earthquake is mostly concentrated in the column beam nodes.To ensure the anti-earthquake effect of the column beam node,while ensuring the basic concept of"strong column and weak beam",it is tried to use the steel core column in the core area instead of the high-strength concrete in the core area,reduce the steel density in the core area,improve the anti-seismic performance of the column beam node,so as to truly realize the"strong column and weak beam".
