结果表明,计入楼梯踏步板对框架结构的自振周期、刚度分布及构件内力影响较大,对框剪结构有一定影响,对剪力墙结构影响不大。
The result of the analysis shows that consideration of stairs in calculating greatly affects the natural period , stiffness distributing and internal forces of members in frame structure . The effect becomes light in frame shear structure and can be ignored in shear wall structure .
