Cold-rolled ribbed steel structure design points: The minimum reinforcement ratio selection. Due to the design value of the tensile strength of steel CRB550 grade level is 1.71 times the HPB235 CRB600H cold rolled steel rebar prices, when the reinforced concrete structure using CRB550 grade steel, can be reduced by a minimum configuration of steel reinforcement ratio. Thus greatly reducing the total amount of reinforcing steel and steel consumption. Seismic housing height should be higher than the current maximum applicable national standard "design of concrete structures." Cold-rolled ribbed steel structure design points: as prescribed shear reinforcement. Steel can be used as non-seismic requirements of reinforced concrete shear wall buildings and seismic intensity of 6 degrees, 7 degrees and 8 degrees (C) of reinforced concrete frame houses a wall structure, shear wall structure and part of the frame-supported shear force distribution muscle wall structure of shear walls. But the bottom-level seismic level to strengthen parts of the distribution of shear reinforcement should be used hot-rolled ribbed steel bars.
