A concrete slab assembling system comprising: -a reinforced concrete slab (1); -a supporting column (2); -a supported column (3), having a bottom-end with a reference outer diameter thereof; -an interface adaptor (10) for placement between the supported co ...
Design formulations for calculation of bond strength in structural concrete members usually include a number of parameters such as the stress acting in the reinforcement, the concrete cover and the diameter of the reinforcing bars. These parameters are act ...
The ultimate strength of reinforced concrete slabs is frequently governed by the punching shear capacity, which may be increased with addition of traditional fitments such as reinforcing steel, headed studs or shear heads. In addition to these traditional ...
It is recognized that most damage to reinforced concrete structures is caused by insufficient durability rather than by low strength. In most cases, the quality and thickness of the cover concrete (‘‘covercrete’’) determine the service life of the structur ...
This paper illustrates a study on the punching shear strength of reinforced concrete slabs in fire conditions. To this end, a set of experimental data on the punching strength of heated slab specimens was interpreted by adapting the well-known Critical She ...

In this study we developed an experimental method to identify the impact force on a reinforced concrete slab. A transfer function obtained experimentally between the acceleration response and the force history applied to a point of the structure was used. ...
There is currently a lack of established calculation method for the geotechnical design of heat exchanger piles. Thermo-mechanical effects are ignored and large overall security factors are therefore applied. This paper presents a new geotechnical numerica ...
The paper considers the impact of multiple shareholder-oriented governance practices on R&D decisions. Based on a sample of 5,528 firms belonging to 110 large French listed business groups, our results substantiate the idea that shareholder-oriented govern ...
The dynamic traffic assignment (DTA) problem is to find the state of a transportation system where demand (travel behavior) and supply (network performance) are mutually consistent. The difficulty of solving this problem with mathematical rigor led to the ...
Reinforced concrete flat slabs are extensively used in buildings and parking garages. Their design is governed by deflection at the serviceability limit state and punching shear at the ultimate limit state. When no punching shear reinforcement is provided, ...
