Structural Walls in Earthquake Resistant Structures:Analytical Investigation -Dynamic Analysis of Isolated Structural Walls -Parts A and B,

摘要

The objectives of the first part of this analysis are: (1) to evaluate the relative influence of various structural and ground motion parameters on the dynamic response to shear forces and deformations in critical regions of structural walls; (2) to determine estimates of critical force and deformation requirements in hinging regions of structural walls corresponding to different combinations of earthquake intensity and the significant structural parameters;and (3) to correlate data on critical dynamic response obtained in (2) with data from laboratory tests of isolated walls under reversing loads to arrive at recommendations on design force levels. The second part of the program,which involves the static analysis of representative wall sections under combined flexure and axial load over the full range of deformation,includes: (1) determining the influence of different design parameters on the characteristics of moment-curvature diagrams,including ductility of typical wall sections; (2) developing charts (interaction diagrams) which can serve as bases for the design of walls in earthquake-resistant structures;and (3) examining the applicability of certain rules proposed to define the hysteretic moment-curvature characteristics of wall sections under reversing loads.
