It is possible for certain building structures to encounter both the seismic load and blast during their service life. With development of economy increase security demand, need design against multi-hazard becoming more obvious. Therefore, damage analysis under combined action multiple hazards has become a very urgent requirement disaster prevention reduction. In this paper, refined finite elem...

4-legged bridge steel truss piers provide support for gravity, transverse, and longitudinal lateral loads of bridges. Allowing a controlled rocking response for seismic resistance of 4-legged truss piers requires the development of design equations considering ground motions in two horizontal directions and vertical excitation. First, the static kinematic and hysteretic bi-directional behavior ...

Abstract For increasing the production capacity of existing oil and gas wells, adding, or modifying equipment with more sophisticated process is necessary. One effort by addition compressors such as on a minimum wellhead platform facility, which are installed top side platform. In to weight topside, must be supported jacket, this installation makes become sensitive seismic loads. This paper dis...

Abstract Lateral forces (wind, seismic) generated in RC buildings are major design criteria against structural collapse. Shear walls offer effective ways to provide resistance such lateral loads. The present study investigates the drift and defection control of symmetrical by providing core corner shear walls. Different limiting were determined four seismic zones (Zone-1 Zone-4) Bangladesh, bas...

This paper comprehensively evaluates the Modal Pushover Analysis (MPA) procedure against the ‘‘exact’’ nonlinear response history analysis (RHA) and investigates the accuracy of seismic demands determined by pushover analysis using FEMA-356 force distributions; the MPA procedure in this paper contains several improvements over the original version presented in Chopra and Goel (2002). Seismic de...

response modification factor (r-factor) is one of the seismic design parameters to consider nonlinear performance of building structures during strong earthquake. relying on this, many seismic design codes led to reduce earthquake loads imposed to the structure. the present paper tries to evaluate the r-factors of conventional concentric braced frames (cbfs) and special moment frames (mrfs) in ...
