Cold-rolled ribbed steel structure design elements: other construction requirements. Plate, with reinforced walls minimum spacing maximum and minimum diameters of the reinforced concrete slab bottom reinforcement force of not less than 6mm factory outlets CRB550, the Ministry of board configurations negative moment reinforcement diameter not less than 8ram Buy CRB550, the reinforced and roofing and distribution of the maximum spacing of the exposed rib structure is generally not more than 200ram; minimum diameter distribution of steel of not less than 5mm, the maximum spacing should not exceed 250ram. Cold-rolled ribbed steel structure design elements: as specified shear reinforcement. Seismic house height should be higher than the current maximum applicable national standard "design of concrete structures." Shear wall with steel configuration, and its distribution muscle of the minimum reinforcement ratio, axial compression ratio, bound edge components and set the edge member structure should be consistent with existing national "Design of Concrete Structures," the required standards.
