The reduction of green-house gas emissions is one of the global challenges that our society is facing and the production of cement plays a major role because concrete is the most used material worldwide. For every 1000 kg of cement produced, 900 kg of CO2, ...
Punching shear failures of structural concrete members have been the focus of attention of numerous works presented over the last decades. Although various rational approaches have been developed to predict these failures, there is still no unanimity on a ...
Reinforced concrete flat slabs constitute one of the most common and efficient modern construction methods. The design of such structural system might be governed by a brittle failure in the vicinity of the slab-column connection associated to punching she ...
Since the first applications of structural concrete, the shear behaviour of one-way slabs without transverse reinforcement has been largely investigated. Nevertheless, currently in the scientific community there is no general agreement on the mechanisms of ...
This paper deals with of a new type of steel-concrete connection for composite beams. The connection is an alternative solution for steel-concrete composite bridges suitable for prefabrication and fast erection. The composite action of the beam is establis ...
Reinforced concrete slabs without shear reinforcement under concentrated loads near linear supports are typical cases of bridge deck slabs, transfer slabs or pile caps. Such members are often designed or assessed in shear/punching shear with code provision ...
The fatigue safety of the reinforced concrete (RC) deck slab of a sixty-year-old steel-concrete road viaduct is questioned based on the results of code-based "re-calculation". Since strengthening intervention would lead to major costs, detailed investigati ...
This study investigates the effect of reinforced concrete cracking on the performance of thermo-active piles subjected to traction force. A newly developed finite element code that is within the framework of the load-transfer approach is employed to simula ...
The presence of damage in a railway bridge alters its stiffness and consequently, its static and dynamic response to loading. The dynamic response of a railway bridge to loading produces a dynamic response in the passing vehicle, potentially enabling detec ...
