moment-resisting frames have extensive usage in earthquake-prone areas and high ability in energy dissipation.after the earthquake in northridge 1994,kobe 1995 fixed connections of steel structures have shown poor performance and generally they were caught brittle fracture of beam flange weld to the column.in order to remedy to avoid similar situations in future earthquakes,researchers introduc...

The excitation of ion azimuthal surface oscillations with extraordinary polarization by light ion beam is studied analytically. Beam-plasma system consists of a cylindrical metal waveguide filled partially by cold magnetized plasma and light ion flow rotating around the plasma column. Dependencies of the beam instability growth rate on the system parameters (plasma and beam densities, value of ...

Abstract: Reduced Beam Section (RBS) and Drilled Beam Section (DBS) are seismic moment resistant frame connections, introduced after 1994 Northridge earthquake. RBS connection has been tested under cyclic loading and showed acceptable performance. In this paper, seismic behavior of Drilled Beam Section (DBS) connection is studied numerically using finite element method. A drilled beam section ...

Abstract: A finite element model is verified accurate enough to simulate the static test of one reinforced-concrete frame with specially shaped columns subjected to the loss of a ground corner column. As the frame sustained loads primarily depending on the beam resisting mechanism in the test, four related parameters, namely the height of beam section, rebar ratio of beam, rebar ratio of slab a...

Indonesia is a country that prone earthquakes. Therefore, knowledge of earthquake-resistant building construction needed in reducing the risk damage caused by There are several methods planning, one which pushover analysis method. Pushover nonlinear static method structure subjected to gravity loading and displacement-controlled lateral loads continue increase through elastic inelastic behavior...

Plentiful studies are reported on the semi-rigid behavior of joints between open section H shaped beam and column, but researches focusing on the semi-rigid performance of joints between square/rectangular hollow section (SHS/RHS) column-to-H shaped beam is to lag a lot. Most studies shows that when the SHS/RHS column connecting the H beam without internal diaphragm, the joints behavior is semi...
