Shear Design of RC Structural Walls


Abstract eng:
The Los Angeles Tall Buildings Structural Design Council (LATBSDC) and Pacific Earthquake Engineering Research Center Tall Buildings Initiative (PEER TBI) performance-based design guidelines for structural wall shear design for tall reinforced concrete core wall buildings are reviewed. Provisions in the two documents are nearly identical, except for the recommended capacity reduction factor , which is 1.0 for the LATBSDC document and 0.75 for the PEER TBI document. In this study, reliability methods were used to assess the current shear design criterion; various statistical parameters were examined for shear demand and shear controlled test results and ACI318-11 code provisions were reviewed to establish statistical parameters for shear capacity. The results suggest that use of =1.0, along with the use of appropriate expected material properties, produces an acceptable probability of failure, whereas the use of =0.75 appears excessively conservative. However, due to a lack of experimental tests on walls that yield in flexure, limitations on curvature ductility or plastic rotation demands are recommended in the plastic hinge regions to avoid potential degradation in shear capacity.
