Seismic overstrength factor
http://db.nzsee.org.nz/2009/Poster68.pdf Webprescribes that the design elastic seismic forces can be reduced by the product of a seismic force-reduction factor (Q´) and a system overstrength factor (R). The factor Q´ is a function of a ductility factor (Q) and the natural period of the structure (T). The factor R is a function of T and a characteristic period of the soil (Ta). A value ...

Weboverstrength factor, 0, and the deflection amplification factor, C d, indicated in Table 12.2-1 shall be used in determining the base shear, element design forces, and design story drift. The selected seismic force-resisting system shall be designed and detailed in accordance with the specific requirements for the WebNov 2, 2016 · In seismic design some members may be required to be designed to an overstrength load. In addition, the lateral system subjected to seismic forces may be required to have some redundancy. In RISA-3D, this is done by creating load combinations with the Omega (overstrength) and Rho (redundancy) factors applied to the earthquake …

WebThe overstrength factor was found to be in the range of 1.29 to 2.33. Also, member ductility factors for the most critical beams and columns were plotted against calculated overstrength factors for all structures separately and are illustrated in figures 4 to 5. From this figure, it can be possible to obtain the overstrength factor iberia routesWebFig. 1 shows a typical seismic design for pump system. In this study, the results of automatic software design were compared with those of manual designing method.
