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 ...
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 ...
Punching shear of reinforced concrete flat slabs supported on columns is a failure mode in which the slab fractures around the column. This type of failure is sudden and can be catastrophic in nature. Punching shear generally governs the ultimate limit sta ...
Design methods for shear in reinforced concrete structures typically rely upon shear transfer through cracks, which depends upon the crack opening and sliding displacements and the roughness of the crack surfaces. The effectiveness of shear transfer throug ...
In multi-storey buildings, columns are usually not continuous through the slabs to enhance ease of construction. Consequently, in slab–column joints, slabs have to carry column loads in addition to the shear and bending moments due to loads applied to the ...
In this study, the nonlinear seismic analysis of a typical three-dimensional concrete faced rockfill dam is reported. Three components of the Loma Prieta (Gilroy 1 station) earthquake acceleration time history are used as input excitation. The dam under st ...
Rehabilitation of deteriorated concrete bridges is a heavy burden from the socio-economic viewpoint. Novel concepts for the rehabilitation of concrete structures must be developed. Ultra-High Performance Fibre Reinforced Concretes (UHPFRC) provide the stru ...
In this paper, the strength of prestressed girders with low amount of shear reinforcement or with defective anchorage is investigated by means of a test programme carried out at the Ecole Polytechnique Fédérale de Lausanne on 10 prestressed and 2 reinforce ...
Proceedings of the 9th fib International PhD Symposium in Civil Engineering2012
An original concept is presented for the durable rehabilitation and strengthening of concrete structures. The main idea is to use Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) complemented with steel reinforcing bars to “harden” and strengthen ...
The use of the structural adhesive bonding technique is well established in the aircraft and automotive industries where, in most cases, joints can be fabricated indoors under controlled conditions. In the civil engineering domain, however, load-bearing st ...
