| 摘要： | In order to extend the latest findings on the in-plane shear behavior of rectangular unreinforced masonry (URM) wallettes with soft-layer bed joints and gain insight into the possible influence of flanges, two series of static-cyclic shear tests on I-shaped (flanged) URM wallettes have been conducted. The wallettes were made of standard Swiss clay blocks and standard cement mortar including a rubber granulate soft layer placed in the bottom bed joint. The test results show that the flanges considerably increased the horizontal force resistance and the initial stiffness of the I-shaped wallettes compared to rectangular wallettes. Further, it appeared that the presence of a soft layer can provide for significant seismic response modification by reducing the initial stiffness and significantly increasing the displacement capacity of the I-shaped wallettes. An analytical model based on discontinuous stress fields is proposed to predict the horizontal force resistance of the I-shaped wallettes with soft-layer bed joints. |
