在我国现在的多高层建筑中,钢筋混凝土结构应用最为普遍,其中钢筋混凝土框架结构是最常用的结构形式。因为其具有足够的强度、良好的延性和较强的整体性,目前广泛用于地震设防地区。钢筋混凝土框架结构具有良好的抗震性能,然而未经合理设计的框架结构会在地震作用下产生较严重的震害。结构抗震的本质就是延性,延性是指构件和结构屈服后,在承载能力不降低或基本不降低的情况下,具有足够塑性变形能力的一种性能。
In our country many high-rise buildings, the most common application of reinforced concrete structures, including reinforced concrete frame structure is the most commonly used form of structure. Because of its sufficient strength, good ductility and strong integrity, is currently widely used in earthquake fortification areas. Reinforced concrete frame structure has good anti-seismic performance, but without reasonable design of the frame structure will produce more serious earthquake damage. The essence of seismic resistance of structures is ductility. Ductility refers to a property with enough plastic deformation ability after yielding of components and structures without decreasing or almost no decrease in carrying capacity.
