The present study is concerned with the simultaneous optimization of the size of components and the arrangement of connections for performance-based seismic design of low-rise SPSWs. Design variables include the size of beams and columns, the thickness of the infill panels, the type of each beam-to-column connection and the type of each infill-to-boundary frame connection. The objective functio...

The existence and (non-)uniqueness of rigid multibody problems with impact, contact and friction is discussed by means of the renowned Painlevé paradox. Different approaches to solve such contact problems, their pros and cons and their connections are discussed.

A quick group search optimizer (QGSO) is an intelligent optimization algorithm which has been applied in structural optimal design, including the hinged spatial structural system. The accuracy and convergence rate of QGSO are feasible to deal with a spatial structural system. In this paper, the QGSO algorithm optimization is adopted in seismic research of steel frames with semi-rigid connection...

This paper presents the development of a composite cold-formed steel (CFS)-rubberised concrete (RuC) semi-rigid moment-resisting connection suitable for framed building structures. The comprises built-up tubular beam and column sections connected using side-plate screwed fasteners infilled with rubberised concrete. A detailed finite element analysis validated against physical tests is employed ...
