ANALYSIS OF A PRECAST SEGMENTAL BRIDGE WITH RCC BRIDGE USING CSI BRIDGE SOFTWARE

Bridges are those structures which built to span physical obstructions without closing the way underneath such as a water body, valley, or roads the purpose is to provide passage over obstructions. Precast bridges with segmental structure are commonly used for long span, due to researchers increasing interest in bridge modeling by using various span condition to check deflection of segmental bridge and RCC bridge, segmental bridge shows better results in comparison to RCC bridge, which is economical for longer spans, as the span increases then the most important factor dead load also increases. On increasing the length of span, the requirements of cross girders (diaphragms) in RCC bridge will also increases as to get desired effectiveness between main girders. In this research the contribution of different factors on shear strength, deflection of segmental bridge and RCC bridge has been investigated.
