由我院公路系主持完成的交通部课题,桥梁空间结构设计理论,1986年10月通过交通部组织的评审,1988年荣获交通部科技进步三等奖。该课题涉及面宽、研究范围较广,在研究中分为了三个子课题进行研究和探讨:(1)压扭破坏试验研究。压扭联合作用是一种常见的结构受力形式,但在以往和现行设计规范中尚无有关压扭强度的校核公式。课题组通过大量混凝土矩形柱和圆柱(管)的压扭破坏试验和尺寸效应研究,在实测数据的整理分析基础上,在我国首次提出了混凝土构件压扭破坏曲线的经
The Department of Transportation, presided over by the Department of Highway, completed the project of the Ministry of Communications and the theory of bridge space structure design. In October 1986, it passed the review organized by the Ministry of Communications and won the third prize of scientific and technological progress of the Ministry of Communications in 1988. The subject involves a wide range of research scope is broader, in the study is divided into three sub-topics for research and discussion: (1) compression damage test. The joint action of compression and torsion is a common form of structural stress, but in the past and the current design specifications there is no proof formula about the compression strength. The research group through a large number of concrete rectangular column and cylinder (tube) compression and torsion failure test and size effect study, based on the analysis of the measured data, the first time in China put forward the concrete component compression torsion damage curve
