Setback irregularities are considered where discontinuity between adjacent stories is excessive. This irregularity caused the probability of high damage at structures subjected to strong earthquake motion. For this purpose, study was conducted by modeling steel special moment frame (SMF) using a finite element calculation program with nonlinear static analysis compared Padang city’s response sp...

this paper is a continuation of [uniformities and covering properties for partial frames (i)], in which we make use of the notion of a partial frame, which is a meet-semilattice in which certain designated subsets are required to have joins, and finite meets distribute over these. after presenting there our axiomatization of partial frames, which we call $sels$-frames, we added structure, in th...

Many recent research studies focused on the development of innovative seismic resilient structures by chasing objectives minimising both damage and repair time, hence allowing definition able to go back undamaged, fully functional condition, in a short time. In this context, present study investigates an type self-centring damage-free steel column base (CB) connection its beneficial effects whe...

Steel extended end plate bolted connections are recommended to be widely utilized in special moment-resisting frame subjected to monotonic loading. Improper design of steel beam to column connection can lead to the collapse and fatality of structures. Therefore comprehensive research studies of beam to column connection design should be carried out. Also the performance and effect of corrugated...

Abstract The aim of the present research is to increasing stiffness structure against lateral loading. In study increase we have four load resisting elements are considered such as shear wall, core bracing system and tube in compare all models with bare frame structure. Here an ordinary moment building G+13 stories located over a medium soil considered. symmetric number bays will be kept 5 alon...

Wave-propagation effects can be useful in determining the system identification of buildings such as the densely instrumented University of California, Los Angeles, Factor building. Waveform data from the 72-channel array in the 17-story moment-resisting steel frame Factor building are used in comparison with finiteelement calculations for predictive behavior. The high dynamic range of the 24-b...

Performance based seismic design (PBSD) is an alternative to code based approaches to design or evaluation of structures that fail to yield a more direct relationship between a seismic event and the corresponding structural performance of a building; this generally leads to over-conservatism. This paper presents a case study on the alternative procedures used in the performance based design of ...
