Abstract Moment resisting connections are mainly designed to transfer bending moments and shear forces. Generally speaking, the design strength of a moment connection can be classified as full-strength (moment capacity equal or greater than that connected member) partial-strength (the less member). Similar remarks made regarding stiffness defining rigid semi-rigid if compared member. In past, h...
The present paper proposes the use of stepped cross section devices on steel frames aiming at reproducing a pre-established target push-over curve. To this aim Limited Resistance Plastic Device (LRPD) to be inserted along selected structural members is proposed. following two main specific features for LRPD are required: any elastic flexural stiffness variation original member must avoided; an ...
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...
Incremental Dynamic Analysis (IDA) procedure is now considered as a robust tool for estimating the seismic sidesway collapse capacity of structures. However, the procedure is time-consuming and requires numerous nonlinear response-history analyses. This paper proposes a simplified Modal Pushover Analysis (MPA) procedure for IDA of RC moment-resisting frames. The proposed method uses the dynamic...
