1980～1982年期间,苏联中央建筑结构科学研究所与钢筋混凝土科学研究所一起,对先前已开始的地震荷载作用下多层框架房屋钢筋混凝土柱的斜截面强度继续进行了研究。地震时多层框架房屋钢筋混凝土柱的损坏和破坏分析,以及计算估计都表明,在柱子中除了有很大的反复剪力和弯矩以外,还可能出现变化的轴向压力,而且在一定的条件下,轴向力会由压力变成为拉力。这种压力的变化特性和很大拉力的产生,将
Between 1980 and 1982, together with the Institute of Reinforced Concrete Science, the Central Institute of Building Structural Science of the Soviet Union continued research on the oblique section strength of reinforced concrete columns of multi-story frame buildings under seismic loading that had previously been initiated. The damage and failure analysis of reinforced concrete columns in multi-story frame buildings during earthquakes, as well as calculations and estimates, indicate that in addition to the large shearing and bending moments in the columns, there may be varying axial pressures, and in certain cases Under conditions, the axial force will change from pressure to tension. This change in pressure characteristics and the production of large pull forces will
