【摘要】 本文给出了正交异性板在多种平面应力边界条件下的应力分布解析表达式，由此提出了多筒高层框筒（或剪力墙筒体）内力与位移计算的正变异性板板块法理论．该方法是基于力法体系及形变协调条件的半解析法，可方便地应用于多筒筒体或多室梯形箱梁等折板结构分析。更多还原

【Abstract】 The high-rise multioell framed-tube building structure is considered as a olthobopic folded plate struCture and is discretized into orthotropic plate elments (for flange and web frames) and cantilever beam elements (for comer columns). The analytical expression of intemal forces and displacements of the building are given based on the orthotropic plate theory in plane problem and based on the deformation compatibility conditions of the frame and comer colunm along their connection lines. The semi-analytical method for shear lag effect and internal force distribution of bundled-tube building is proposed. The results are compared with that of other merhods.更多还原
