Concrete, as the most widely used construction material, is associated with a high environmental impact. Within present study, structural optimization method of choice to counter this issue. The entire process, from optimization, design, experiments and numerical simulation outlined. Embedded in framework design competition (Concrete Girder Optimization Competition 2021), bridge between enginee...

Bridges are common and important constructions to overcome different obstacles in any transportation network. Variations bridge types include variation span length, statical system, construction material, methods sustained loads. Choosing the suitable system is affected with several factors such as time, availability of materials, available budget, contractors’ background one most layout road n...

Pre-stressed steel-concrete composite beams are widely used in bridges around the world. Loads during service life of may cause failure form fracture studs near ends bridge girders. The effect stud on residual static capacity and fatigue girders is not well investigated. Therefore, this study presents numerical investigations into effects progressive shear connectors performance remaining post-...

The durability of precast structures often depends on quality execution the connections between structural elements. Essential also is their design and proper exploitation. This paper focuses magnitude damages as well repair methods used for a slab, which consists prestressed double T slab elements supported inverted girders. It was found that during execution, girders were forced to fit dowel ...
