摘 要: | 低周反复试验表明,短肢墙结构墙肢纵向应变分布近似符合平截面假定。据此,提出对称结构内力计算模型,并经试验结果校验;然后,按此计算模型建立了结构中主墙肢的剪力、轴力和弯矩负载率计算公式,为截面设计提供了内力分析模式。

Study on internal force distribution in symmetry shallow-section shear wall structure |
| |
Abstract: | Base on experiment results, the Bernoulli's assumption is taken for the longitudinal strain distribution in shallow section shear wall structures (SSSW). Consequently, the internal force assessment approach is put forward for the SSSW structure, which is ratified by the experiment results later. With these approaches, the load effect bearing ratio in the principal limb is determined in twin limbed SSSW structure. The conclusion may be used in the practical member section design. |
