This paper presents a framework (named Bridge_Sim) that aids contractors in planning bridge deck construction using computer simulation. The proposed framework estimates the time and cost required for construction of bridges' decks. Seven construction methods are included in the proposed framework. These are: cast-in-place on falsework, steel bridge construction, cantilever carriage, pre-cast b...
Background of the research: A conventional box-type structure is generally used in constructing core/shear wall, internal frame, and steel box girders. Tube-in-Tube with single multiple tubes reduces shear lag effect lateral deformation a tall tubular structure. Purpose: However, present study focuses on behavior modified form beam, i.e., beam outstanding flanges. Thus, this analyzes flanges co...
Metro systems provide an efficient, convenient, and expeditious way to travel around crowded routes. Because these are established in cities, residential buildings close metro viaducts significantly affected by structure-borne noise (SBN). Although most previous studies developed SBN prediction with a focus on the accuracy computational efficiency of specific bridge type, only limited parameter...
This presentation describes the concepts involved in design and construction of a reinforcement-free bridge deck intended to provide cost effective, durable and more rapid construction for highway bridges. The new wide flanged or bulb tee precast prestressed concrete girder sections currently used in bridges allow for a shorter effective span for the bridge deck because of the wide girder flang...
