Abstract:The design method of the connecting joints of the translation precast concrete facade wall panels was studied in a practical project. First, panel type division and movement mode selection principle of the wall panel was put forward considering building functional requirements, and the connection structure between facade wall panel and the steel beam of main structure was researched according to a translational precast concrete facade wall panel movement needs. Then, combined with the existing national standards, the performance goals were determined for the precast concrete facade wall panel. According to the facade wall movement mode, mechanical models and the performance-based design method of connecting joints under different working conditions were put forward. Finally, a concrete engineering example was given. The proposed design method can realize the performance goals of the translational precast concrete facade wall panel with elasticity under frequent earthquake, elasticity of the connecting joint under fortification earthquake and non-yielding under rare earthquake, and the safety performance of the wall panel can be guaranteed.
Keywords:translational precast concrete facade wall panel;connecting joint;seismic performance
