砖混结构是我国民用建筑中采用最多、历史最长、数量最大的一种结构。由于这种结构属于脆性材料,具有刚度大、延性小的特点,在历次强震中都受到破坏。1975年海城地震后,京津两市对房屋进行了抗震加固,经1976年唐山地震证明,在有中期强震预报的地区进行震前抗震加固是减轻地震灾害的一项有效措施。一、正确理解《鉴定标准》提出的设防思想我国《工业与民用建筑抗震鉴
The brick-concrete structure is one of the most used, longest, and largest structures in China’s civil construction. Because this structure is a brittle material, it has the characteristics of large rigidity and low ductility, and it has been damaged in all previous strong earthquakes. After the Haicheng earthquake in 1975, the Beijing and Tianjin cities carried out aseismic reinforcements for the houses. After the Tangshan earthquake in 1976, it was proved that the seismic strengthening before the earthquake in areas with strong medium-term earthquake prediction is an effective measure to reduce the earthquake disaster. I. Correctly understand the fortification ideology proposed in the “Appraisal Standard”. China’s “Industrial and Civil Buildings”
