【摘要】 现浇楼盖板对RC框架结构的破坏机制有着重要的影响,它对梁端抗弯承载力有一定的增强作用。不同的板厚和楼板类型对RC框架结构的破坏形态影响不同,文章利用有限元数值分析软件ANSYS分别建立不同楼板厚度和不同楼板长宽比各两组模型,研究它们在三种地震波作用下的破坏机制以及裂缝分布,得出板厚变化和板的长宽比变化对RC框架结构破坏形态的影响规律,对梁端实际抗弯承载力计算提出建议。更多还原

【Abstract】 Cast-in-place floor has a significant impact on the failure mechanism of reninforced concrete frame structures, it has a certain enhancement effect on the flexural capacity of beam.Different plate thickness and slab types have different influence on the failure pattern of reinforced concrete frame structures. This paper sets up two group model with different plate thickness and different length-width ratio by ANSYS, a kind of finite element numerical analysis software. Studying their failure pattern and crack distribution in the three kinds of seismic waves to find the influence on the reinforced concrete frame structures by the change of plate thickness and length-width ratio.Offering a proposal to compute the practical flexural capacity of the end of beam.更多还原
