Seismic provisions in the Saudi building code

Seismic provisions in the Saudi building code Authors A Shuraim, M Al-Haddad, R Al-Zaid, R Mirza, K It is generally uneconomical and unnecessary to design a structure to respond in the elastic range to the maximum earthquake-induced inertia forces. Thus, the design seismic horizontal forces prescribed in the seismic codes (IBC 2003, ASCE-7, SBC 301), are generally less than the elastic

Seismic Analysis and Design of a Multi-Storey Building

Recently the design of RC building to mitigate seismic loads has received a great attention. Since Saudi Arabia has low to moderate seismicity, most of buildings were designed only for gravity load. The objective of this paper is to analysis design RC building located in the most active seismic zone region in Saudi Arabia to mitigate seismic loads.

Seismic Vulnerability of RC Shear Wall Building with a

26/10/2015· Recent seismic events in low-to-moderate seismicity regions of Saudi Arabia have led to concerns on the vulnerability of RC buildings constructed in Saudi Arabia up to mid-1990’s. These buildings were designed for gravity loads only, and potential for damage during seismic event is high. Buildings with dome at the roof level are an architectural feature in many buildings.
