摘要:
钢筋混凝土剪力墙在竖向荷载的作用下可能会发生因稳定性不足所引起的屈曲破坏,使剪力墙不能有效发挥其优异的承载能力和抗震性能。根据钢筋混凝土剪力墙在实际工程结构中的受力特点,对其边界条件进行分析和合理简化,建立了对边简支对边自由的正交各向异性板理论分析模型,采用位能驻值原理,推导出了竖向荷载下剪力墙发生平面外失稳破坏时对应的临界应力表达式。根据所得临界应力计算公式,研究了剪力墙的高度和厚度、纵向钢筋直径和间距等因素对钢筋混凝土剪力墙临界应力的影响规律,并进一步探讨了改善竖向荷载下钢筋混凝土剪力墙稳定性的有效方法。
Abstract:
With vertical load, buckling failure of reinforced concrete shear walls might occur because of its insufficient stability. The excellent load capacity and seismic performance of shear wall could not take effect.The boundary conditions were analyzed to be simplified reasonably based on the loading features of reinforced concrete shear wall in practical engineering. An analytical model of or thotropic slab with two simply supported boundaries and two free boundaries was built. The critical stress formula of shear wall at out-of-plane buckling failure under vertical load was obtained using the principle of stationary potential energy. According to the critical stress formula obtained , the influences of the height and thickness , diameter and space of longitudinal reinforcement of shear wall on the critical stress were discussed. The further research about the effective measures to improve the stability of shear wall under vertical load was completed.
