Abstract:Code for design of concrete structures (GB 50010—2002) provides a approximate method to calculate the normal section compressive load-bearing capacity of concrete eccentric compression member with longitudinal steel reinforcements uniformly provided along web of sections. On this basis, Technical specification for concrete structures of tall building (JGJ 3—2002) proposes a simplified method. But there are some problems about the effective depth of section hw0, the stress of steel reinforcement in the tension side σs, the relative depth of limiting compression zone ξb and the distance e between acting point of axial compressive force and point for resultant of forces of tensile longitudinal steel reinforcements in JGJ 3—2002\,JGJ 3—2010. Possible corrections about these parameters were proposed. The examples indicate that the Nu-Mu curves calculated by the suggested method based on the corrections accord well with the method in GB 50010—2010 and RESPONSE-2000.
Keywords:RC shear wall; eccentric compression capacity; code for tall building; Nu-Mu curve
