建筑工程上还普遍使用二级钢时，那在建房时，若很富有的话，建筑螺纹钢筋里面可添加抗震钢，若要是一般的住宅楼要用什么材质的钢材钢筋呢？
Construction is also widely used when the two grade steel, and that in the building, if it is rich, the construction of rebar can be added to the seismic steel, if the general residential building to use what material steel, steel bar?
住宅楼用什么材质的螺纹钢筋这还要根据我国自然地理条件的不同而采用不同。钢筋在混凝土中主要承受拉应力。变形钢筋由于肋的作用，和混凝土有较大的粘结能力，因而能更好地承受外力的作用。钢筋广泛用于各种建筑结构、特别是大型、重型、轻型薄壁和高层建筑结构。

What kind of rebar is used in residential buildings, which should be different according to the natural geographical conditions of our country. Steel bars are mainly subjected to tensile stress in concrete. Because of the function of rib and the greater bond ability of concrete, deformed steel bar can bear the effect of external force better. Reinforcement is widely used in a variety of building structures, especially large, heavy, light, thin-walled and high-rise structures.
如果房子的楼板是预制板的那么里面的螺纹钢筋就是冷拔预应力筋， 通常在楼板内使用，做板底筋或板负筋，大跨度的板也用HRB400钢筋做底筋和负筋，房子梁板柱采用什么钢筋都是安全的，所以没有必要了解是用什么螺纹钢筋，房子出现危险很多原因是施工过程中的钢筋构造要求达不到设计要求或使用了“瘦身钢筋”造成的，很少是结构计算选型错误造成的。
If the house floor is prefabricated as rebar inside is drawn prestressed reinforcement, usually used in the floor, do the slab reinforcement or negative reinforcement plate, long span plate with HRB400 steel bars and end of negative reinforcement, reinforced by what Liang Banzhu house are safe, so there is no need to know is what is the structure of reinforced rebar, house construction process requirements to meet the design requirements or the use of thin steel caused by the risk of a lot of reasons, is rarely caused by the errors of calculation and selection of structure.
