Response modification factor (R factor) is one of the seismic design parameters to be considered in evaluating the performance of buildings during strong motions. This paper has tried to evaluate the response modification factor of concrete coupled shear wall structures with various length/depth ratios of spandrel beams. The effect of diagonal reinforcement of spandrel beam was also evaluated o...

• Forty-seven dowelled cross-laminated timber (CLT) connections were tested. Increased row spacing and end distance significantly increased ductility. Reinforcement by screws or threaded dowels with nuts enhanced performance. 3-ply (135 mm), 5-ply (175 mm ), 7-ply (275 mm) CLT panels employed. Overstrength ductility of determined. Dowel embedment tests performed to determine theoretical overstr...

Seismic hazard assessment in several sites worldwide depends on two or more seismic sources. Many countries affected by subduction zones have strong motions earthquakes originated at least important In Mexico, interplate (subduction process) epicenters located the Pacific coast with hypocenter depths less than 45 km and intraplate (intermediate-depth earthquakes) normally inside continent depth...

Conventional design of steel plate shear walls SPSWs assumes that 100% of the story shear is resisted by each infill panel. Following this approach, strength provided by the boundary frame moment resisting action, which provides the SPSW with overstrength, is neglected. While this design assumption has a positive impact on seismic performance of SPSWs, no analytical work has been done to quanti...

Concentrically braced frames and eccentrically braced frames are efficient seismic resistant systems but they are generally prone to develop storey collapse mechanisms. As underlined in some previous papers with regard to eccentrically braced frames, this tendency depends on the overstrength factors and damage distribution capacity factors resulting from the use of common design procedures. In ...

Turkish Building Seismic Code (TBSC), which was published in 2018 and became effective 2019 prescribes a two-stage loading method for designing of building with rigid podium. In the first stage, podium is modeled as massless structure only mass superstructure considered modal response spectrum analysis. The seismic design forces are computed using this model appropriate modification coefficient...
