9. perimeter tube and interior core wall 筒中筒

10.bundled tubes 成束筒

11.shear lag 剪力滞后

句子

1. 在混凝土高层结构中，成束筒的概念就是将两个或多个独立的筒连成一束以减小剪力滞后效应。

The concept of bundled tube in concrete high rises is to connect two or more individual tubes in a bundle with the object of decreasing the shear lag effects.

2. 当两个或多个剪力墙通过梁系或板系连接起来，系统总刚度超过单独剪力墙刚度的总和，这是因为梁或板的连接使系统受力，使梁板成为组合单元，限制了单独悬臂作用。

When two or more shear walls are interconnected by a system of beams or slabs, the total stiffness of the system exceeds the summation of the individual wall stiffness because the connecting beam or slab restrain the individual cantilever action by forcing the system to work as composed unit.

3. 在框架剪力墙体系中，框架的变形基本上属于剪切型，而剪力墙的主要变形由弯曲引起，类似于像悬臂构件。水平变形的一致性产生了二者的相互作用。

In shear wall- frame, the frame basically deforms in a so-called shear mode while the shear wall mainly responds by bending as a cantilever. Compatibility of horizontal deformation produces interaction between the two.
