摘要
抗低温抗震是混凝土建筑结构质量判断标准之一。我国属地震多发国家,需要考虑抗震设防的地域辽阔,研究钢筋混凝土结构的抗震性能在我国具有充分的必要性,本文分析探讨钢筋混凝土结构与砌体结构的基本抗震设计思路和方法。此外,结构钢对温度很敏感。当温度降低时,钢的响应从延展状态向易碎状态逐渐递增过渡。金属材料韧性的丧失可以通过核查低温时的应力—应变的关系观测。
Low temperature and seismic resistantis one of the structure quality criterion. China is an earthquake-prone country,it needs to consider the vast earthquake-proof. It is necessary to study the seismic performance of reinforced concrete structures in China. The article analyzes the seismic resistant design and methods of reinforced concrete structures and masonry structures . In addition,the structural steel is very sensitive to temperature. The response state of steel transits from extension to fragile when the temperature decreases. The loss of metal toughness can be observed by checking stress - strain relations at low temperature .
