- Abstract:
- To investigate the influence of key link space on whole performance of insulation composite shear wall, three groups of specimens were designed and made base on three forms of key link spaces of 300, 400, 500 mm, respectively. Through comparative experiments, the failure mechanism and loadvertical displacement curves of specimen were obtained. According to existing problems of the traditional shear wall, a new insulation composite shear wall was put forward. The study results show that the failure pattern of specimen is a kind of brittle fracture. The key link space has little influence on axial compressive capacity of specimen, and has some influence on the stability of mortar out of plane and failure location of structure. The formula used to calculate the axial compressive capacity of reinforced concrete columns in concrete code should be multiplied by reduction factor when used to calculate the bearing capacity of insulation composite shear wall.
