摘要
为了提高高层建筑连梁在地震中的作用,将连梁的混凝土材料替换成ECC材料,并对高层结构进行了多遇地震和罕遇地震下层间位移角、基底剪力和楼层加速度等分析,分析表明,ECC连梁在多遇地震和罕遇地震下,使得结构的周期有所提高,结构的刚度降低,但结构的层间位移角、基底剪力和楼层加速度也能得到明显减小,具有较强的耗能能力,有效地提高了结构的整体抗震性能。
In order to improve the role of high-rise building coupling beams in earthquakes,the concrete material of coupling beams is replaced by ECC material,and the inter-story displacement angle,base shear force and floor acceleration of high-rise structures under frequent and rare earthquakes are carried out.The analysis shows that under frequent and rare earthquakes,ECC coupling beams increase the period of the structure and reduce the stiffness of the structure,but the inter-story displacement angle,base shear force and floor acceleration of the structure can also be significantly reduced,which has strong energy dissipation capacity and effectively improves the overall seismic performance of the structure.
