1988年8月在日本举行的第九届世界地震工程会议(Ninth World Confernece on Earthquake Engineering 9WCEE,1988.8.2～9.东京—京都)上,报导了几种砼新结构(高强砼、钢纤维砼、劲性砼和预应力砼等)的近期研究结果,兹简介如下,供参考。一、高强砼结构为了适应高层建筑的发展需要,减轻结构自重,扩大室内空间,高强材料(高强砼和高强钢砼)已在地震区得到实际应用。高强砼抗压强度(fc′)一般40～
At the 9th World Earthquake Engineering Conference held in Japan in August 1988 (Ninth World Confernece on Earthquake Engineering 9WCEE, 1988.8.2~9. Tokyo-Kyoto), several new structures were reported (high-strength concrete, steel fiber concrete). The results of the recent studies, such as 劲, 预, and prestressed 砼, are summarized below for reference. First, the high-strength concrete structure In order to adapt to the development needs of high-rise buildings, reduce the weight of the structure, expand the indoor space, high-strength materials (high-strength concrete and high-strength steel file) have been practically applied in the earthquake area. High-strength concrete compressive strength (fc’) generally 40 ~
