| Research Abstract |
The pile cap is a very important member connecting the column, pile, foundation beams. There are two kinds of vertical members, columns and pile, in a pile cap. So, the seismic behavior of pile cap is more complicated than the beam column joint.
We performed lateral load reversal tested of subassemblages with one pile, column, foundation beam and pile-cap, and considered the earthquake resistant performance of pile cap. The diagonal shear crack strength and ultimate shear strength can be estimated by the prediction method for usual RC beam-column joints to apply the vertical member section to the average between the pile, the column and the pile cap section or that between column and pile cap. But in this research, the small diameter pile was applied, which was smaller than the column section in case of the low buildings. The ultimate shear strength was increased by mounting the shear reinforcements.
