“概念设计”就是按照结构的破坏形式和破坏过程,运用抗震设计原则,全面合理解决抗震设计中的基本问题。抗震“概念设计”应从以下几个方面考虑。 1.房屋体形要简单 房屋体形不规则,平面上凹凸变化,立面上高低不平等均不利于抗震。 2.结构力求对称 非对称结构即使在地面平动作用下,也会发生扭转,造成严重破坏,所以整个建筑或其独立单元应该力求结构上下对称,质心与重心重合或偏离较少。 “Concept design” is to apply the principles of seismic design in accordance with the structural damage form and destruction process to fully solve the basic problems in seismic design. Seismic “conceptual design” should be considered from the following aspects. 1. The shape of the house should be simple. The shape of the house is irregular, the bumps on the plane change, and the inequality on the facade is not conducive to earthquake resistance. 2. Structure seeks symmetry The asymmetric structure will be twisted even if it is used on the level of the ground, causing serious damage. Therefore, the whole building or its independent unit should strive to make the structure up and down symmetrical, and the center of mass coincides with or deviates from the center of gravity.
