  • The design method of shear wall's boundary elements is one of the problems that have not been solved perfectly.The lateral displacement mode of cantilever shear wall in limit state is set up,and the plastic hinge rotation is used to define the fortification objective of each seismic grade.The relationship between plastic hinge rotation and cross section's curvature,axial compression ratio and relative height of compression zone are deduced.The length of confined zone can be determined by plane-section assumption theory,and the transverse reinforcement characteristic value is determined by the stress-strain relationship of confined concrete.The comparison of 20 shear wall specimens' calculation results and test results illustrates that this design procedure is feasible.The length of confined zones and the transverse reinforcement characteristic values of boundary element in different seismic grades and axial compression ratios are proposed.
