Experimental study on superposed concrete shear wall with concealing column at vertical seam

The use of quasi-static test (Push-over Analysis), study superposed concrete shearwall with concealing column at vertical seam for seismic properties. Analyze this new shearwalls' damage characteristic, stiffness degradation curve and hysteresis curve. Comparison of the in-situ shear wall structure test results ,study this new shear walls' seismic performance and integrity.
