• Simplified building model for seismic assessment using dynamic analyses. Model suitable non-shear-type buildings as it accounts beams flexibility. Torsional behaviour of irregular accurately captured. Remarkable reduction computational time. Validation on a 3D reinforced concrete moment resisting frame building. Seismic safety assessments at the large-scale are paramount importance densely ur...

The significance of the seismic rotational components have been overlooked in the seismic evaluation of structural behavior. As researchers have measured seismic components more accurately using sensitive rotational velocity sensor, it was observed that the magnitude of rotational components is considerable and could not be neglected. Hence, some parts of seismic damage or failure of structures...

When a steel moment-resisting frame deforms horizontally, H-shaped beams are subjected to the flexural moment gradient. Generally, rigidly connected box section columns possessing large fork restraint. Further, continuous braces on top flange effectively prevent lateral buckling. In this paper, buckling behavior of continuously braced with restraint under gradient is clarified theoretically and...

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 ...

the proposal lateral load pattern for pushover analysis is given in two forms for symmetric concrete buildings: 1-(x/h)0.5 for low-rise and mid-rise buildings, 2- sin(πx/h) for high-rise buildings. these two forms give more realistic results as compared to conventional load patterns such as triangular and uniform load patterns. the assumed buildings of 4, 8, 12, 16, 20 and 30 story concrete bui...
