The use of heavier trucks demanded upgrading of a twenty-seven year old bridge in Winnipeg, Manitoba, Canada. Analysis of the precast prestressed concrete girders using the current AASHTO Code indicates a deficiency in the shear capacity. Shear strengthening using Carbon Fibre Reinforced Polymer (CFRP) sheets provides a low-cost solution by increasing the speed of construction and reducing traf...

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...

Enhancing the ease of construction fillers and large-span floors their overall mechanical performance is critical for prefabricated hollow slabs in modular building structures. Therefore, we propose a novel assembly integral two-way floor structure (8.4 × 8.4 m) consisting permanent (BDF ribbed steel mesh box) three precast one-way hollow-core with I-shaped flexural sections to address above pr...

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...
