摘要:
通过单向地震作用下的时程分析,指出了现有空冷岛结构体系抗震性能的不足,对增设与不增设防屈曲支撑的结构体系进行了对比,并对双向地震作用下防屈曲支撑空冷岛结构体系的受力性能进行了初步研究,最后给出了一种能够实现超长防屈曲支撑的方法。结果表明:增设防屈曲支撑后的空冷岛结构基本规避了地震作用下的整体扭转变形影响; 当双向布置的防屈曲支撑均发生屈服后结构扭转变形有增大的趋势。
Abstract:
Through time history analysis under single-component earthquake excitations, the deficiencies of the seismic performance of the exiting structural system of air-cooled condenser were pointed out. Comparisons between the structural system with and without buckling-restrained braced(BRB)supporting systems were carried out. The mechanical behaviors of BRB structural system of air-cooled condenser under two-component earthquake excitations were preliminarily studied, and a connecting procedure of the super-long BRB was proposed. The results show that the influences of overall torsion deformation under earthquake excitations are prohibited efficiently by adding BRB to the existing structural system of air-cooled condenser, and the torsion deformation has an increase trend after yielding of the BRB in two-component arrangement of the structural system.
