Seismic Behavior of Flanged Masonry Shear Walls

摘要

The report summarizes the results of a research project representing preliminary studies into the flexural strength, ductility, and seismic response of T-Section Masonry Walls. The project consisted of two sections: (1) analytical studies resulting in the development of dimensionless design charts for flexural strength, stiffness and ductility capacity of unconfined and confined T-section walls loaded in the two opposite directions parallel to the web; and (2) shake table testing of a full-size wide-flange T-section wall under sinusoidal and simulated earthquake acceleration input focusing on the expected asymmetric response, and the shear lag in the flange. Results confirmed the importance of the directionality of strength and stiffness characteristics.
