Capacity design is an important tool that enables controlled ductile response of structures when subjected to earthquakes. The need for specific capacity design requirements for walls coupled by deep coupling beams, however, is often overlooked and it is a ...
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 ...
Proceedings of the 7th International Conference on Structures in Fire - SiF2012 (Eds. M. Fontana, A. Frangi, M. Knobloch)2012
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. ...
Reinforced concrete (RC) culverts under high fill have been widely used in the construction of expressways and railways. Based on the results of a field survey, various types of structural damage to RC culverts occur during construction and service periods ...
This paper presents the first part of a series of uniaxial cyclic tests on lap-splices. The work is conducted within the framework of a project on the seismic behaviour of existing, poorly detailed bridge piers which are typically constructed with a lap-sp ...
In January 2011, the Swiss Society of Engineers and Architects (SIA) published a series of standards for existing structures. The standard entitled 'existing structures-bases for examination and interventions' specifies the principles, the terminology and ...
Flat slabs are commonly used in Switzerland but also in north America and in many European countries. Slab bridges are also a typical solution for crossing of motorways for example. In both cases, supporting a slab by columns is justified by the simplicity ...
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, ...
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 ...
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 ...
