多年来,笔者曾参与了多项各类工程建设项目的抗震设计审查,从中发现如下一些普遍性问题,希望引起同行们的注意。1、缺乏岩土工程勘察资料或资料不全。设计缺少必要的依据。2、结构的平面布置。外形不规则、不对称、凹凸变化尺度大、形心制裁心偏大,同一结构单元内,结构平面形状和刚度不均匀不对称,平面长度过长等。3、一个结构单元仙采用两种不同的结构受力体系。如一半采用砌体承重,而另一半或局部采用全框架承重或排架承重;底框砖房
Over the years, I have participated in a variety of projects of various types of seismic design review, from which found some of the following general problems, hoping to attract the attention of colleagues. 1, lack of geotechnical investigation or incomplete information. Design lacks necessary grounds. 2, the layout of the structure. Irregular shape, asymmetry, large variation of concave and convex, centripetal centripetal center is too large, the same structural unit, the uneven shape and stiffness of the structure uneven, the plane length is too long. 3, a structure unit cents using two different structure force system. If half of the masonry load-bearing, while the other half or partial use of full-frame load-bearing or rack-mounted; bottom frame brick
