Seismic Retrofitting RC Structures with Precast Prestressed Concrete Braces- ABAQUS FEA Modeling
Precast prestreesed concrete braces are a new method for seismic strength of Concrete Structures which has the following benefits: a) no wet concrete work in construction site b) No bolt or anchorage to the existing frame c) easy to apply d) short construction period e) low construction cost, to evaluate seismic performance of strengthened structure a model consist of existing frame and concret...
متن کاملTailoring Experimental Strategy and Setup: the Long Story of the Seismic Behaviour of Precast Structures
Devising the most appropriate testing strategy and conceiving a mock-up “as simple as possible, but not simpler” is the challenge which has to be taken whenever a research programme does involve experiments. Optimizing the experimental programme reduces the risk of either wasting time and resources or missing some of the fundamental ingredients of the structural behaviour because of oversimplif...
متن کاملSeismic Displacement Demands for Hybrid Precast Concrete Shear Walls
This paper presents an analytical investigation on the peak lateral displacement demands of “hybrid” precast concrete panelized shear wall structures under seismic loading. The hybrid wall structure investigated uses a combination of mild [i.e., Grade 400 (U.S. Grade 60)] steel bars and highstrength unbonded post-tensioning (PT) strands for lateral resistance across horizontal joints. The analy...
متن کاملSeismic Design Considerations for Precast Concrete Shear Wall Connections
The performance of precast shear wall panel structures subjected to earthquakes relies on the behaviour and integrity of the connections between the panels. The current lack of knowledge on the seismic behaviour of precast wall connections limits the use of such systems in earthquake areas. This paper presents results of an extensive experimental program undertaken at the University of Manitoba...
متن کاملDesign of Hybrid Precast Concrete Walls for Seismic Regions
This paper presents an ongoing research project on the behavior and design of “hybrid” precast concrete wall structures for use in seismic regions. Hybrid precast walls utilize a combination of mild (e.g., Grade 60) steel and high-strength unbonded post-tensioning (PT) steel for flexural resistance across horizontal joints. The mild steel reinforcement is designed to yield in tension and compre...
