Horizontal loading due to earthquake or wind is usually the governing action for design of reinforced concrete cores in medium to tall buildings. Building cores designed to resist these actions must be dimensioned to resist tributary vertical loads and lar ...
Flat slabs are commonly used in buildings due to their easiness of construction and economy. In order to keep these advantages, columns are usually not continuous through the slabs in multi-storey buildings. In these cases, the slabs are subjected to large ...
This paper describes an experimental study of two joint configurations, one with only reinforced polymer concrete (RPC) infill, the other with RPC infill and bonded GRP plates, to overcome shear and moment discontinuities in GRP bridge decks transverse to ...
Ultra High-Performance Fibre-Reinforced Concrete (UHPFRC) combines high strength, deformation capacity and low permeability. This makes UHPFRC particularly suitable as a strengthening and protective layer for application to existing reinforced concrete str ...
Over the past century, the use of flat slabs in buildings and especially in parking garages has been growing as it is an economic and efficient solution. Flat slabs are easy to build and have, through their smaller depth, an economical and architectural ad ...
An emerging technique for strengthening of reinforced concrete (RC) slabs is to add a layer of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) with steel rebars as an external tensile flexural reinforcement. This paper presents the results of an ...
Punching shear reinforcement is increasingly used in flat slabs as an effective solution to increase their strength and deformation capacity. Several punching shear reinforcing systems have been developed in the past, such as studs, stirrups or bent-up bar ...
The influence of shear on the rotation capacity of one-way slabs without shear reinforcement is investigated in this paper by means of an experimental study. The experimental program consisted of 11 slab strips 8400 mm (331 in.) long and 450 mm (17.7 in.) ...
This paper reviews the experimental and modeling work that has been carried out concerning the behavior of fiber-reinforced polymer (FRP) composites in fire since the 1980s. The first part focuses on the thermophysical properties and temperature responses, ...
A large number of medium and small span bridges in Switzerland and in other countries are slab bridges, often prestressed, multi-span and supported by columns. Punching in such structures is typically governing at failure. So far, the knowledge of the infl ...
