STRENGTH EVALUATION OF PRECAST CANTILEVER WALLS ALLOWED SLIP FAILURE OF VERTICAL JOINTS

A strength calculation method of RC cantilever wall panels　(Part 2)

Abstract

This paper discusses a strength evaluation method of precast multi-story shear wall system which allows slip failure of the vertical joint between wall panels and boundary columns. Shear force of the vertical joint is transmitted by cotters and the joint reinforcements of beam position. Ultimate strength of the wall system is evaluated by adding strength of a wall panel by the calculation method shown in our previous paper and shear forces of the columns. The results of this method were compared with loading tests of the precast wall systems. The calculated values were in good agreement with the experiments.
