An investigation into the time dependency of shear strength of clay brick walls; an approximate approach

Time dependent structural degradation has an adverse effect on the long term performance and safety of structures. The present study mainly investigates time dependency of in-plane shear strength of clay brick walls and tries to enhance individual models for the resistance degradation. It also develops a framework for numerical aging analysis based on multivariable field test data. The results, obtained from the numerical analyses done on the collected data in accordance with ASTM C1531, are then applied to derive suitable resistance degradation functions and predict the uncertain long term shear resistivity of clay brick walls.
