两边连接钢板剪力墙侧边由于受压屈曲产生较大变形,削弱其承载力和耗能能力。在两侧边采取加劲措施可以增强两侧边的稳定性,并在一定程度上提高承载能力和耗能能力。采用ANSYS有限元软件对侧边理想加劲的两边连接钢板剪力墙进行滞回分析,研究在理想加劲情况下,加劲肋对两边连接钢板剪力墙受力模式、承载能力和耗能能力的影响。分析结果表明,理想加劲情况下,拉力带较易产生,也因此提高了承载能力和耗能能力。随高厚比增大,加劲肋的影响相对增大;而随跨高比增大,加劲肋的影响趋于减小。
Both sides of the steel plate connected to the shear wall due to buckling large deformation, weakening its bearing capacity and energy consumption. Stiffening measures on both sides can enhance the stability of both sides, and to some extent, increase the carrying capacity and energy consumption. The finite element analysis software ANSYS was used to analyze the hysteretic behavior of stiffened steel plates on both sides, and the influence of the stiffeners on the stress mode, the bearing capacity and the energy dissipation capacity of the shear walls connected to the two sides under ideal stiffened conditions . The analysis results show that the tension belt is easy to produce under the ideal stiffening condition, and therefore the carrying capacity and energy dissipation capacity are improved. As the ratio of height to thickness increases, the influence of stiffeners increases relatively; while as the ratio of span to height increases, the influence of stiffeners tends to decrease.
