Typical applications for post-installed rebar connections consist in overlapping joints with existing reinforcement or anchoring of the at a slab beam support. At cold state it may be shown by testing that system can develop same bond resistance safety margin as cast-in-place rebar. Consequently, anchorage length and lap rebars calculated according to Eurocode 2 provisions. However, when subjected temperature, decay properties systems is significantly more dramatic than rebars. The paper...
The decay in the local bond performance of reinforcement bars concrete due to exposure high temperature is often investigated performing pull-out tests on steel rods embedded center specimens.The are generally performed residual state i.e. upon cooling down room temperature.However, this approach neglects not only detrimental effects splitting strength bond, but also application a sustained load during heating phase, as real applications.This paper investigates between and after temperatures...

Commercial malls and similar large low-rise multi-storey building typologies are often constructed employing precast frame structures. Wall cores surrounding stairs elevators occupy a small area if compared to the of floors. Generally, these need be decoupled from structure, which is designated as lateral load resisting system, given that, rigidly connected frame, their high stiffness would draw seismic actions not compatible with capacity or economical/feasible foundation systems. The...
In post-installed connection in reinforced concrete structures, bonded anchors are commonly adopted when elevated mechanical performances required. Such may be significantly impaired by adverse service conditions, above all temperature variations with respect to room ambient one. It is also generally acknowledged that the curing impact on anchor performances, extent main existing qualification procedures assess behavior cured at different temperatures, particular below zero Celsius degree....
Abstract An experimental campaign carried out on prestressed bridge beams corroded in a marine environment is analyzed order to understand the failure modes related deterioration phenomena and setup models for capacity assessment. Three main failures were identified: shear web, zones with prestress loss flexural strands tension; this last mode becomes dominant increasing corrosion. A truss model was used flexure resistance, considering presence of both bottom pretensioned breaks draped...
During the last decades, different technologies to anchor steel elements in concrete were proposed. The present work presents results of a preliminary investigation new connection characterized by single plates that are directly bonded on surfaces. response was experimentally investigated under both tension and shear actions. Specific conditions influencing behavior assembly discussed, with particular reference presence cracks crack cycling concrete.
