the present research is concerned with the determination of ductility, over-strength and response modification factors of coupled steel shear wall frames. three structural models with various numbers of stories, bay width and coupling beam height were analyzed using static pushover and incremental nonlinear dynamic analyses. the ductility, over-strength and response modification factors for the...

The worldwide use of precast concrete frames leads to an increase in the need for the investigation of efficient precast connections, particularly in the seismic regions. The current paper provides a numerical and experimental study on a dry precast connection. Experiments were conducted to validate the finite element method in the laboratory of the University of Science and Culture. To verify ...

Recent research efforts have focused on the development of performance based seismic design methodologies for structures. However, the seismic design rules prescribed in the current Canadian Highway Bridge Design Code (CHBDC) is based largely on force based design principles. Although a set of performance requirements (performance objectives) for different return period earthquake events have b...

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...

In 1993, a project began at the University at Buffalo under the title “Longevity and Reliability of Sliding Seismic Isolation Systems” with the support of MCEER. The objectives of the project were then defined as the collection of laboratory and field data on the behavior of sliding bearings and the qualitative prediction of the long-term frictional properties of these bearings. In 1995, the au...

Hybrid moment frame come together with reinforced concrete columns with structural steel beams (RCS). This Composite system provides several key advantages over current steel or concrete moment resisting frame. Past studies have shown this system to be efficient in both design and building stage while able to keep sufficient strength and necessary ductility in seismic zone.Although past researc...

Many researches have been currently conducted on the effects of fault distance on structures revealing that their seismic response can differ according to their distance from the fault. Suspension bridges due to their long period and high flexibility can be more sensitive to this phenomenon, especially in vertical vibration. Since the engineers tend to use longer spans, the length factor should...

Seismic design modification factors (SDMFs) control the estimated force and displacement to structures during seismic events. codes recommend similar SDMFs for short andlong-span structures. Therefore, this study investigated effect of span length on steel frames with high ductility. For purpose, nine three different lengths 5, 10, 15 m were selected designed according specifications ASCE/SEI 7...
