对混凝土局部受压的破坏现象和破坏机理进行阐述,并对局部受压承载力计算方法进行分析,指出目前计算中存在的若干问题及对相关问题的考虑,提出局压影响区三类间接钢筋的计算取用方法和布置原则,为局部受压问题的深入研究及其计算方法的完善提供一些理论参考。
Failure phenomena and failure mechanism of concrete local compression are elaborated. Calculation methods of local compression load bearing capacity are analyzed. Some problems in actual calculations are brought forward as well as the consideration relevant to these problems. It is proposed that the calculation and selection method and distribution principle of three kinds of indirect reinforcement in local compression influence zone. All these can be served as theoretical references for making further researches on local compression and perfecting calculation methods of local compression.
