Seismic Evaluation of Steel Plate Shear Walls in Different Configurations [PDF]
Journal of Rehabilitation in Civil EngineeringSteel plate shear walls (SPSWs) are a cost-efficient system to resist seismic lateral loads. Post-buckling strength, tension field action, and high energy absorption capacity are among the advantages of SPSWs. A beam-coupled SPSW consists of two pairs of

Time history analysis formulation in SCAD FEA software [PDF]
Journal of Measurements in Engineering, 2018 This paper provides the formulation of the problem of forced vibrations of structures, which has the following peculiarities: equations of motion are formulated in absolute coordinates allowing to take into account the asynchronous excitations of the supports, smoothing of the time functions for forced displacements with the help of Hermite polynomials,

Time History Analysis on Precast Building Connections
International Journal of Recent Technology and Engineering (IJRTE), 2019 Construction industry is one of the most important factor for the development of the country. Precast buildings are one of the major development in construction technology, this technology helps to reduce the construction time and cost. Precast building construction is widely improved at present in India. The Growth of the precast building construction
