This article provides a behaviour analysis of moment resisting joints with curved endplates. is new type connection that can be used for joining steel beams to the circular hollow section (CHS) columns by means bolts. Some researchers apply Eurocode model without considering differences in calculation schemes and assumptions, such as using general an equivalent T-stub tension. Consequently, man...

the aim of the present paper is to evaluate the influence of the soil- foundation- structure interaction (sfsi) effects on the component demand modifier factor of concrete gravity beams based on asce 41-06 standard. to this end, the beam on the nonlinear winkler foundation approach is employed which is a simple and efficient method. at first, four sets of 3-, 6-, 10- and 15-storey concrete mome...

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 ...

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...

The present study addresses optimal design of reinforced concrete (RC) columns based on equivalent equations considering deformability regulations of ACI318-14 under axial force and uniaxial bending moment. This study contrary to common approaches working with trial and error approach in design, at first presents an exact solution for intensity of longitudinal reinforcement in column section by...

This paper suggested a new connection protocol, adding cover-plate between shear links and column, which was used to enhance moment and shear carrying capacity of beam, relax the restriction and assure the sufficiency development of plastic deformation of the link, and dissipate more earthquake energy. Considering the scale ratio of 1:3, the experimental data was achieved by a specimen under cy...

In the present paper an improved formulation devoted to optimal design problem of a special moment resisting connection device for steel frames is proposed. This innovative called Limited Resistance Plastic Device (LRPD) and it has been recently proposed patented by some authors. It thought be preferably located at extremes beam, connecting beam end cross section with relevant column. The typic...

The SidePlate moment connection system, developed by MNH-SMRF Systems, Inc., looks different because it is different. SidePlateTM's unique trademark geometry provides physical separation between the face of column and end of beam by means of parallel full-depth side plates. This innovative feature ensures the elimination of all brittle behavioral uncertainties responsible for the unprecedented...
