本节主要讲授与无梁楼板剪力墙(Flat slab and shear walls)相关的专业词汇、关键语法、复杂复合句的理解与翻译。

    (1) 剪力墙的作用 (Function of shear walls)

    (2) 剪力墙的设置 (Location of shear walls)

    (3) 无梁楼板剪力墙设计细节 ( Design considerations of flat slab and shear walls)

【选择题】

1. Because planner shear walls are efficient lateral load carriers only in their plane, it is necessary to provide walls in two        directions.

(A) orthogonal;  (B) horizontal;    (C) vertical;    (D) normal.

【简答题】

1. Why is flat slab and shear walls adopted?

【词汇英译汉】

1. lateral-load-resisting element

2. planar shear wall

3. orthogonal orientation

4. cantilevers

5. overturning moment

【答案】

1. 侧向荷载约束单元

2. 平板剪力墙

3. 正交方向

4. 悬臂构件

5. 倾覆力矩

【句子汉译英】

1. 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。

2. 因此，许多工程师通过设计剪力墙来承担横向荷载，完全忽略了框架的作用。

【答案】

1. 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.

2.Many engineers, therefore, ignore the frame action altogether by designing the shear walls to carry the total lateral loads.
