《建筑结构》作业3(国外英文资料) (2) the type of masonry: the stiffness of the brick wall is less than the solid wall, and the value should be reduced. Composite brick masonry rigidity is good, [] the value increases accordingly. (3) the spacing of the horizontal wall: the distance between the horizontal wall, the stability and rigidity of the wall. On the other hand, the distance between the horizontal wall is more stable and the stiffness is poor. When calculating the high thickness ratio, the method of calculating the height of the wall is considered. (4) supporting conditions: the wall of the rigid plan house, the column of the house (building) shall be assumed to be the non-moving hinge, the supporting space is small, the value can be improved. In the case of elasticity and rigid elasticity, the value of the wall and column should be reduced. (5) of the masonry section forms: Windows and doors hole wall is variable cross-section wall, the stability of the wall is not the mouth of the cave walls to poor, rules, allowing high thickness coefficient correction than [] yield reduction. (6) the importance of the components and the use of the house: the non-load-bearing wall belongs to the secondary component, and the load is the body weight of the wall, and the value can be improved. Houses that vibrate when used, should be reduced. What is the characteristic of steel in different forms of destruction under various loads? Answer: under various loads, the steel will have two completely different forms of destruction, namely plastic damage and brittle fracture. Plastic damage fracture are fibrous, dark color and destroy the former has the larger plastic deformation and obvious necking phenomenon, long time and deformation, easy to find and take effective remedial measures in time, usually does not cause serious consequences. Brittle fracture with smooth and glossy grain. Because there is no obvious sign before the brittle damage, the damage can be caused by the failure to detect and
