一、概述20年来,在工民建钢筋混凝土结构领域,一个相当普通的质量问题就是结构的裂缝问题,结构裂缝成了质量通病之一,且有日趋增多的趋势。它已影响到正常的生活和生产,并困扰着大批工程技术人员和管理人员。国内外关于荷载作用下钢筋混凝土构件的设计都有自己的经验公式,并已? First, an overview of 20 years, in the field of workers and civilians to build reinforced concrete structure, a fairly common quality problem is the structural crack, structural cracks have become one of the common quality problems, and there is an increasing trend. It has affected normal life and production and has troubled a large number of engineers and managers. At home and abroad on the role of load under the design of reinforced concrete members have their own empirical formula, and has?
