带抗震墙框架结构在地震荷载作用下,受力复杂。由于抗震墙强弱不同、所在层不同、建筑高度不同或偏心扭转不同都会引起各层梁柱内力的变化。 本文通过大量系统的计算和理论分析,发现梁柱地震内力的变化尽管错综复杂,但都是有规律的、并收敛在有限的幅度内。这些规律不仅为框架构件的通用定型提供了理论依据而且对个体工程的抗震设计也有一定参考意义。
With the earthquake-resistant wall frame structure under earthquake load, the force is complex. Because of different strengths of seismic walls, different layers, different building heights or different eccentric torsion, the internal forces of various layers will change. In this paper, through a large number of systematic calculations and theoretical analysis, it has been found that the internal forces of Liangzhu Earthquake, despite their intricacies, are regular and converge within a limited range. These laws not only provide a theoretical basis for the universal design of the framework components, but also have some reference significance for the seismic design of individual projects.
