防止工程结构连续倒塌的概念控制
|
摘要
依托已有的工程结构倒塌案例,提出"概念控制"的概念,比较概念控制与概念设计的不同,介绍概念控制的力流、诱因、破坏机制、破坏准则等影响因素,并结合实际工程案例进行分析,最后给出几点需特别注意的构造措施。研究表明,概念控制作为一种新的分析方法,有一定的工程可行性。
Based on the existing cases in the progressive collapses of engineering structures,this article proposes the conceptual control,compares the difference between the conceptual control and the conceptual design,and introduces the factors of influencing the conceptual control such as the force flow,incentive cause,failure mechanism,failure criterion.Combining with the analysis of the real project case,it finally presents several structural measures that should be paid particular attention to.The research shows that the conceptual control,as a new type of analytical method,has a certain engineering feasibility.
