摘要 This work proposes two aspects about construction materials abased on Wenchuan post-earthquake investigations. According to different feature failure modes in various damaged structures and the cause of the damage to the effects of the loading during the ground motion, the structural failures were found related to low cycle fatigue (LCF) properties of building steel. The hitherto research development is presented briefly. The characters of cycle response of the steels are tested and discussed. During the post-earthquake reconstruction process, the disposal of huge quantities of earthquake demolition waste brought great challenges. Utilizing the waste concrete taken from earthquake-stricken area as recycled coarse aggregate (RCA) in the new concrete is conducted. Furthermore, the application perspective of RCA is discussed.
