Comparison between damage to multi-storey brick buildings and strength of walls is made in this paper. From the evaluation of earthquake resistance for 65953 pieces of wall in 301 brick buildings, cracking resistant coefficient K_0 for areas of different intensities and collapse resistant coefficient K_(10)n for area of higher intensities are given respectively for the aseismic design. So K_0 may also be used as a quantitative measure of earthquake intensity. Meanwhile, the comparison between damage...

Comparison between damage to multi-storey brick buildings and strength of walls is made in this paper. From the evaluation of earthquake resistance for 65953 pieces of wall in 301 brick buildings, cracking resistant coefficient K_0 for areas of different intensities and collapse resistant coefficient K_(10)n for area of higher intensities are given respectively for the aseismic design. So K_0 may also be used as a quantitative measure of earthquake intensity. Meanwhile, the comparison between damage to multi-storey brick buildings and their strength in Tangshan urban district reflects the effect of site conditions. Rock sites and soft soil sites with intercalation of silt clay are both favourable to such buildings.

本文进行了震害与砖墙体强度的对比,结果表明在唐山市区,楼层平均抗震强度系数K_1大于0.25的多层砖房,一般不倒塌。文中又研究了不同烈度区砖墳体抗震强度系数的开裂临界值K_0。上述结果为多层砖房按抗裂抗倒双重没防准则进行设计提供了技术参数。文中指出K_0值亦可作为地震烈度的定量指标。文中通过对比,还反映了唐山市区的烈度异常现象。

The horizontal seismic load is traditionally regarded as the decisive role in damage to structures. In 1957, the author pointed out: "The traditional viewpoint is incorrect, actually, it is vertical seismic load that plays the important role in destruction". The author proved his viewpoint continually these years.From the amount of vertical seismic load determined in many state standards, it seems that traditional viewpoint probobly stems from two main ways. (1) Many earthquake records show that the peak accelerations of vertical ground motion are only about the half of horizontal ground motion; (2) Structures have little magnification effect for vertical ground motion. Many motion appearances of components, bodies or men on ground or structures will be enumerated in this paper to illustrate that the main bases of traditional viewpoint are really serious. In addition it is proved on the bases of damage positions and damage char acteristic of structures at epicentra or at sites far from epicentra that only with the concept of vertical seismic load flaying decisive role can enplain destruction of earthquake more reasonably.

若干年来的传统观点都认为水平地震力对结构破坏起着决定性作用。笔者1957年提出,这些年又继续证明:“传统观点是错误的,实际上是竖向地震力起主要作用。” 从很多国家规范规定的竖向地震力看来,传统观点可能基于两个主要考虑:1.很多地震记录都说明地面竖向加速度只有水平加速度的二分之一左右;2.结构对地面竖向运动没有放大作用。本文将列举大量地面上及结构上构件、物体与人的运动现象来说明传统观点的主要根据是很成问题的。另外,文中还根据震中区和远离震中区很多结构的破坏位置、破坏特征等证明:只有按竖向地震力起主要作用的观点才能给予较合理的解释。
