It has been a growing trend to use cold-formed steel (CFS) sections as primary structural members in low multi-story buildings due their high strength-to-weight ratios, ease of construction and flexibility manufacturing variety cross-sectional shapes. However, CFS frames are not widely used seismic regions; one important reason is that the less redundant joints generally have ductility energy d...

Beam column joint failure has been linked to the partial or whole collapse of reinforced structures, according information gathered during seismic reconnaissance. Under stress, a single beam only limited impact, but beam-column junction might lead structure. The resulting economic damage and human casualties are substantial. Hence, keeping from coming apart is crucial. Recent earthquakes have c...

In order to analyze the post-fire seismic performances of scoria aggregate concrete (SAC) beam-column joints precisely and effectively, one finite element model (FEM) was developed simulate behavior SAC joints. The FEM consists two sequential parts: firstly, heat transfer analysis joints, then by combining temperature field distribution obtained from with mechanical properties after fire, both ...

This paper reviews the provisions given in draft of second-generation Eurocode 8 (EC8) for design and assessment RC beam-column joint against seismic conditions. The analytical bases were recently published by Michael Fardis. A critical discussion models, supported a numerical example, is given. Validation an independent database exterior joints made. final comparison with respect to (i) curren...
