一、建筑物的抗震设防与节点的关系国外多次大地震经验表明,对于多层钢筋混凝土框架,由于结构和材料的可延性,而具有较好的抗震性能。但在强烈地震时,也有不少框架遭到严重破坏,以至倒塌。震害调查指出,破坏部位大多在柱子和节点
First, the relationship between seismic fortification of the building and the node The experience of several large earthquakes abroad has shown that for multi-layer reinforced concrete frames, due to the ductility of the structure and material, it has a good seismic performance. However, in the event of a strong earthquake, many frameworks were severely damaged and even collapsed. Earthquake damage survey pointed out that most of the damage sites are pillars and nodes.
