II. True or false. (each one 4 points, total 20 points) (Score: ) 1.Under the action of specified horizontal force,the maximum elastic horizontal displacement (storey drift of storey is larger than 1.5 times of the elastic horizontal displacement(or storey drift )at both ends of storey is Torsional irregularity. ) ( 2. The general layout principle of shear wall is scattered, symmetrical, and peripheral. ( ) 3.the seismic adjustment coefficient is not introduced when calculating the bearing capacity. ( ) 第1页共1页 4. The main seismic damages of shear wall structure are shear failure of connection beam, shear cracks and horizontal cracks appear on the wall. ( ) 5. For frame structure, the width shall not be less than 100mm when the height does not exceed 15m; when it exceeds 15m, the corresponding increase in height of 5m, 4m, 3m and 2m for 6 degrees, 7 degrees, 8 degrees and 9 degrees, the width shall widen by 10mm.
