Comparative Study of R.C.C & Structural Steel -Concrete Composite Frame for Linear and Non-Linear Analysis MOHD AMIR KHAN M.Tech (Structural & Foundation Engineering) Department of Civil Engineering Al FALAH UNIVERSITY, Faridabad INDIA ---------------------------------------------------------------------***---------------------------------------------------------------------
Abstract –Structural Steel-Concrete composite structures are nowadays very popular owing to their advantages over conventional Concrete and Steel constructions. Concrete structures are bulky and impart more seismic weight and more deflection as compare to Composite Construction combines the better properties of both steel and concrete along with lesser cost, speedy construction, fire protection etc. Hence the aim of the present study is to compare seismic performance of RCC, Steel and Composite building frame situated in earthquake zone IV. All frames are designed for same gravity loadings .The slab is used in concrete and deck slab in composite building. Beam and column sections are made of Either RCC and Structural Steel-concrete composite sections. Equivalent static method and Response Spectrum method are used for seismic analysis and Non-linear static pushover analysis. Software is used and results are compared.
1.1 COMPOSITE DECK SLAB
Composite floor system consists of steel beams, metal decking and concrete. They are combined in a very efficient way so that the best properties of each material can be used to optimize construction techniques. The most common arrangement found in composite floor systems is a rolled or built-up steel beam connected to a formed steel deck and concrete slab. The metal deck typically spans unsupported between steel members, while also providing a working platform for concreting work. The composite floor system produces a rigid horizontal diaphragm providing stability to building.

INTRODUCTION Structural Steel-concrete composite systems have become quite popular in recent times because of their advantages against conventional construction. Composite construction combines the better properties of the both i.e. concrete and steel and results in speedy construction. In the present work included Comparative study of R.C.C. Recent trends in construction industry is to use of steel, reinforced concrete and structural steel-concrete composite member which are functioning together and termed as composite, mixed or hybrid systems. Such systems make use of each type of member in most efficient manner to maximize the structural and economic benefit. An additional benefit provided by composite frame is derived from their excellent fire-resistant properties. Over the past twenty years the composite RCS moment frame systems have been used in the US and Japan. Extensive research is currently underway to better understand the behaviour of such frames. Much of this research aims at experimentally investigating the characteristics of joints between steel and reinforced concrete members and understanding the behaviour of mixed assemblies.
Fig.no.1 DECK SLAB 1.2 COMPOSITE BEAM AND COLUMN A structural steel-concrete composite column is a compression member, comprising either of a concrete encased hot rolled steel section or a concrete filled hollow section of hot rolled steel. It is generally used as a load bearing member in a composite framed structure. Composite members are mainly subjected to compression and bending.
