CAD、PKPM常见问题解析(国外英文资料) The minimum reinforcement percentage of all longitudinal steel bars of the compression component shall be reduced by 0.1 in accordance with the provisions of the table for the use of HRB400 and RRB400. When the strength level of concrete is C60 and above, it shall increase by 0.1. The compression steel of the tension member shall be considered by the side of the compression member. Side all three compression member of longitudinal reinforcement and reinforcement ratio of longitudinal reinforcement and axis tensile component and small eccentric tension members on one side of the steel reinforcement ratio should be calculated on the whole cross section area of the component; Flexural member, and large eccentric tension members on one side of the steel reinforcement ratio shall be deducted by the whole cross section area of compressive flange area (b f - b) h f after cross section area; When the steel bar is arranged along the section of the section of the building, the side longitudinal steel is the longitudinal reinforcement that is placed in the direction of the two sides opposite the force. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- - Stirrup ratio Volume ratio and area ratio 1. The concept: Both of them are in the case of a hoop, so its also called the volume matching band and the area band (1). The area of stirrup ratio (rho sv) : is in the vertical section of stirrup bs (stirrup spacing for wide for component b, s), the area ratio of the stirrup (hoops area of limb Multiply the area of each bar. Calculate the formula: rho sv = Asv/bs = nAsv1 / bs (2).volume with band ratio (rho v) : the ratio of the volume of the band (the total length of the band) to the corresponding concrete volume. The composite b
