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...

In this study, the complex behavior of steel encased reinforced concrete (SRC) composite beam–columns in biaxial bending is predicted by multilayer perceptron neural network. For this purpose, the previously proposed nonlinear analysis model, mixed beam-column formulation, is verified with biaxial bending test results. Then a large set of benchmark frames is provided and P-Mx-My triaxial ...

In the Northridge and Kobe earthquakes, brittle failure of welded beam-to-column connections was observed in steel structures. So, bolted were considered as an alternative to these kinds connections. Extended end-plate con-nection is one most commonly used structure. this article, behavior sloped extended studied. Finite element method investigate connection by ABAQUS software. The main aim stu...

Sonomicrometrics of in vivo axial strain of muscle has shown that the swimming fish body bends like a homogenous, continuous beam in all species except tuna. This simple beam-like behavior is surprising because the underlying tendon structure, muscle structure and behavior are complex. Given this incongruence, our goal was to understand the mechanical role of various myoseptal tendons. We model...

in this paper, the capabilities of displacement curvature derived from static response data for finding the location and severity of damage in euler-bernoulli beams are assessed. static response of a beam is obtained using the finite element modeling. in order to reduce the number of measured nodal displacements, the beam deflection is fitted through a polynomial function using a limited number...

This paper presents a simple displacement-based seismic design method for RC frames with steel damper column. As numerical example, two 10-story frame building models are shown. The results of nonlinear time-history analysis show that the peak displacement at equivalent height is close to target displacement. strength demand beam ends connected columns, and beam-damper column joints, calculated...

The purpose of this study is to ensure that the building structure able withstand required loads and strengths, as well meet applicable technical safety requirements building. With research, it expected create column, beam, foundation products North Sumatra generation can be marketed construction needs in region. result arrangement beams by modeling using ETABS, largest moment found B30 beam sp...
