在施工管理中,发现不少有抗震设防要求的现浇框架工程,在其钢筋制作与绑扎过程中,未能严格遵循《抗震规范》及CG 329(二)所规定的各项构造措施。有些施工人员认为这些构造措施无关紧要,只要受力钢筋的施工满足设计要求即可,却不知对有抗震设防要求的房屋,保证其具有足够的延性和保证其具有足够的强度同等重要。而《抗震规范》所规定的各项构造措施就是为了使结构具有足够的延性,它是保证结构具有较强抗震能力的重要手段。所以,保证了结构的构造措施,即保证了结构具有足够的延性。那么,在有地震力作用时,房屋结构便可通过各构件的塑性变形吸收大量地震能量,从而使房屋结构承受的地震力随结构刚度的降
In the construction management, many cast-in-place frame projects with seismic fortification requirements were discovered. In the production and binding process of reinforcing bars, various structural measures specified in the “Seismic code” and CG 329(2) were not strictly observed. Some constructors believe that these structural measures are not important, as long as the construction of the stressed steel bar meets the design requirements, but it is equally important to ensure that they have enough ductility and ensure that they have sufficient strength for a house with seismic resistance requirements. The various structural measures specified in the “Seismic Code” are intended to make the structure sufficiently ductile. It is an important means to ensure that the structure has a strong ability to resist earthquakes. Therefore, structural measures of the structure are ensured, that is, the structure has sufficient ductility. Then, when there is a seismic force, the structure of the house can absorb a large amount of seismic energy through the plastic deformation of each component, so that the seismic force experienced by the house structure decreases with the structural rigidity.
