Nowadays civil engineering is more concerned with substituting old traditional ways of construction with modern ones. The main objectives are saving effort, money, time…etc. Modern civil engineering has concentrated on solving and facilitating our daily events such as transportation costs and facilitates movement of the beams at the construction sites . To solve this problem, civil engineers considered steel to be the main material in bridge construction, which have a high weight to strength ratio. so the idea of composite material of steel and concrete was suggested to replace the part of steel construction.. except the economic and construction time problems relative to all the construction materials used
through the time, composite material is the most expensive and the most time consuming in construction, but has the
ability for building very quickly and the availability of the main constituents of concrete Hybrid composite beam (HCB) has solved all the previous problems .. In this paper, the Hybrid Composite Beam consisted of combination of concrete , steel and glass fiber-reinforced polymer in an efficient form, is studied as a simplified system to reduce the design requirements of construction of bridges instead of precast concrete beams and accomplishes both quick construction and increased durability. A comparison is to be made between HCB and Precast Concrete Beam in terms of time, transportation facilities and difficulties, and construction requirements. This study is supported by a stress analysis using SAP2000 showing the different response of both of them when subjected to different cases of loading.
