Road traffic loading is a highly variable process with a wide range of complex variables to consider. Consequently, various simplifying assumptions are required to efficiently model heavy traffic events for bridge safety verification, which reduce the accu ...
SUMMARY: This paper investigates the effect of the composite action on the seismic performance of steel special moment frames (SMFs) through collapse. A rational approach is first proposed to model the hysteretic behavior of fully restrained composite beam ...
An original concept is presented for the durable rehabilitation of concrete bridge deck slabs. The main idea is to add a layer of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) with steel reinforcing bars over the concrete slab to create a compo ...
This paper focuses on the numerical modelling of SentryGlas-laminated reinforced glass beams. In these beams, which have been experimentally investigated in preceding research, a stainless steel reinforcement section is laminated at the inner recessed edge ...
In this study the structural response of post-tensioned structural glass beams is investigated. This is done through four-point bending tests on two series of post-tensioned glass beam specimens. The beams consist of three layers of annealed float glass an ...
The addition of a thin overlay of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) to Reinforced Concrete (RC) members is an emerging technique to strengthen and protect existing structures and to design durable new structures. Combining UHPFRC wi ...
Steel-concrete composite bridges with twin-I steel girders and prefabricated slabs constitute an economical and competitive solution for small and medium bridge spans. In recent years they have started to gain their share in the construction market. Howeve ...
With the occurrence of higher and more frequent axle loads on roads, in particular bridge deck slabs are more severely solicitated by fatigue loading. To avoid heavy interventions for strengthening of bridge deck slabs, an improved building material is use ...
In a cellular FRP deck-on-beam bridge, the deck's load response is influenced by the cellular frame's local indeterminacy and by the global indeterminacy due to multiple beams at each support. Thus, the stiffness distributions for both levels of indetermin ...
Due to ever increasing traffic demands the fatigue safety and service life of the bridges of a railway line in Brazil need to be examined. Conventional assessment methods using load models and approaches as suggested in codes lead to conservative results r ...
