Abstract

Abstract This is the scheme planning and structure design of the Zhaojiazhuang Medium Bridge on the Rongwu Highway. The final aim of this study is to come up with a safe, reliable, and practical bridge satisfying both functional and safety requirements and also founded upon real engineering data and onsite conditions. In reference to Changguo Medium Bridge, the project is taking the most favorable geological and hydrological conditions into consideration to meet maximum performance of the bridge within the environment. 1. Design Parameters and Technical Specifications: The deck of the bridge will be designed with a clear width of 8.5 meters, having two shoulders of 0.75 meters. The structural safety class of the bridge is Class I, and it has a design load rating of Highway – Grade I. The main span of the bridge is 20 meters with a five-transverse diaphragm- reinforced concrete simply supported T-beam structure. The main beam span has been calculated to be 1950 cm and with additional precautions in beam size, spacing, and location of reinforcements while determining the structural strength and load-carrying capacity. 2. Scheme Comparison and Choice: Reinforced concrete solid slab bridge, prestressed concrete box girder bridge, steel-concrete composite girder bridge, and reinforced concrete simply supported T-beam bridge are the four bridge alternatives compared for scheme comparison. The alternatives were: Point-wise compared on the structural characteristics, Feasibility in constructability, Economic evaluation, Durability and Maintenance, and site suitability. After a close scrutiny, reinforced concrete simple supported T-beam bridge was utilized on account of having its highest constructability, durability, and economy. 3. Structural Design and Calculation: After the T-beam structure was identified, in-depth structural analysis and calculation of bridge deck, main beam, and diaphragms were conducted. They included permanent and variable load calculation, internal force calculation, and reinforcement design. Location of the diaphragm and rebar location were also optimized to improve overall stability and durability of the bridge as per safety and performance requirements. Keywords: Highway bridge; Scheme comparison; T-beam bridge; Structural design; Structural calculations.
