Cost Analysis of RCC, Steel and Composite Multi-Storied Car Parking Subjected to High Wind Exposure in Bangladesh
Abstract: Steel-concrete
composite constructions in Bangladesh are nowadays very popular owing to their
advantages over conventional concrete and steel constructions. Concrete
structures are massive and allot more seismic weight and less deflection
whereas steel structures instruct more deflections and ductility to the
structure, which is beneficial in resisting earthquake and wind forces.
Composite construction combines the better properties of both steel and
concrete along with lesser cost, speedy construction, fire protection etc. The
objective of this study was to analysis and design ground floor plus 19 storied
R.C.C, Steel and Composite (steel-concrete) multi-storied parking structure’s
frame of same plan using ETABS 2013 software and compare their structural
parameters with estimated cost for required material. All frames are designed
for same gravity and dynamic loadings. The RCC deck-slab is used in steel and
composite frame. Beam and column sections are made of RCC, steel or
steel-concrete composite sections. The composite construction option provided
about 25 % and 18% less cost when compared to RCC and steel structure,
respectively. Comparative study concludes that the composite frames are best
suited among all the three types of constructions in terms of material cost and
benefit added with better structural behaviour.
