A solution technique for the dynamic analysis of asymmetric base-isolated buildings, subject to earthquake ground motion, is presented. To develop the formulation, a yield surface as a function of both shear force and torsion moment of the sliding surface with rigid perfectly plastic behavior is constituted. To achieve the objective, the yield stress is defined by the friction coefficient throu...

An origin-destination (OD) flow is the movement of objects from an origin to a destination. Determining how flows vary across geographic locations helps understand mechanism distributions; however, it has rarely been studied. Here, we propose trend surface model with polynomial functions quantify distribution coordinates in space. This assumes that observed data-record composed value and residu...
