at high elevation. • Fire rating for service and passenger elevator shafts is achieved by simply placing concrete of a determined thickness. • The need for complex bolted or side-welded steel connections is avoided. • Well detail reinforce concrete will develop about twice as much damping as structural steel. Disadvantages:- • Shear walls formed around elevator and service risers require a concentration of opening at ground level where stresses are critical. • Shear wall vertical movements

If GRFP is utilized‚ the portal frame section can be design to consume less steel because GFRP is light weight. Since it has a very high strength to weight ratio‚ being light weight‚ GFRP does not make it loose its strength. Regardless‚ this material still possesses less strength compared to steel. This material is also environment and corrosion resistance‚ so when used as purlins or
