The stiffness of masonry infill walls is commonly neglected in design practice Reinforced Concrete (RC) structures. In fact, the wall may significantly influence seismic performance and dynamic behavior RC buildings. this research, to structural a three-story frame investigated. addition, possible application friction-based support also studied. Full 3D non-linear time history analysis conducte...

OBJECTIVES This paper presents the results of a realist evaluation that aimed to understand how, why and under what circumstances a Red Cross (RC) capacity-building intervention influences the motivation and the performance of RC community health volunteers involved in the delivery of an immunisation programme in Kampala, Uganda. METHOD Given the complexity of the intervention, we adopted rea...

A new method for building a reduced order circuit model, based on symbolic or numerical elimination of the internal circuit nodes, is presented. The circuit passivity is preserved unlike the majority of other approaches. A 1033 node RC circuit is reduced to an admittance with one pole and two zeros for a frequency range of three decades.
