some considerable damage to steel structures during the hyogo-ken nanbu earthquake occurred. among them, many exposed-type column bases failed in several consistent patterns, such as brittle base plate fracture, excessive bolt elongation, unexpected early bolt failure, and inferior construction work, etc. the lessons from these phenomena led to the need for improved understanding of column base...

Abstract In this study, an experimental program was carried out to investigate the dynamic behaviour of post-and-beam mass timber frames, manufactured from LVL structural products, under a sudden column removal scenario. Twenty-five free-fall and two additional static tests were performed on scaled-down frames assembled with three beam-to-column connection types, referred as “Double-beam”, “Meg...

The effects of Northridge (1994) and Kobe (1995) earthquake, intensive analysis testing efforts are currently being sought for higher ways designing seismic resistant steel connections. A connection with RBS (Reduced beam Section) is an acceptable solution to emphasizing a moment can be the most reliable type connection. Considering benefits lack information on resources in Indian standards, an...

This study developed a 1:2 scale model using T-shape steel with one-side bolts to connect square tube column an H-shape beam for quasi-static test investigate the mechanical properties and seismic behavior of semi-rigid joints. Within context, joint’s failure characteristics, hysteresis strain tendency under cyclic load were determined. In addition, this research analyzed force characteristics ...

According to current design practices of steel moment-resisting frames, formation plastic hinges is unavoidable when the frames are supported by conventional column base systems, i.e., exposed-type and embedded-type due unequalized flexural moment demand on top first story columns [1]. Kimura et.al [3] has proposed mid-story pin system avoid from yielding realize beam-yielding mechanism applyin...

Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...
