近些年来,随着物质生活水平的不断提高,我国的私人建房户越来越多,使钢筋混凝土构件(如板、梁和柱子等)走进了千家万户,并发挥着重要作用,这不能不令人感到高兴。不过有些同志由于对钢筋和混凝土两种材料共同工作的性能缺乏较深入的了解,往往会产生一种错觉,误认为混凝土构件内放置的钢筋越多越“牢固”,即所谓“安全”。其实这种看法是不正 In recent years, with the continuous improvement of the material quality of life, more and more private homebuilders have been built in China, which has made it possible for reinforced concrete components (such as slabs, beams, pillars, etc.) to enter millions of households and play an important role.
