Building structures using Precast Reinforced Concrete Wall Panels (PRCWP) are widely used in Romania. An important disadvantage of these buildings is the functional rigidity of the interior space due to the dense distribution of the load bearing walls. Cut-out openings are often required to facilitate direct access from outside or between adjacent apartments. This paper presents a part of research program regarding the effectiveness of using the Externally Bonded Carbon Fiber Reinforced Polymer (CFRP-EBR) composites as seismic retrofitting solution for PRCWPs weakened by cut-out openings. The discussion was focused on the strengthening strategies adopted for both narrow and wide door openings.
In this paper the authors partially summarize the results of a research on glued insulated rail joints with fiber-glass reinforced plastic fishplates (brand: Apatech) related to own executed laboratory tests. The goal of the research is to investigate the application of this new type of glued insulated rail joint where the fishplates are manufactured at high pressure, regulated temperature, glass-fiber reinforced polymer composite plastic material. The usage of this kind of glued insulated rail joints is able to eliminate the electric fishplate circuit and early fatigue deflection and it can ensure the isolation of rails’ ends from each other by aspect of electric conductivity.
The application of a deformation-based analytical approach is presented in this paper to calculate the strength-increase of axially loaded circular columns, strengthened with fiber reinforced polymer and reinforced concrete jackets.
A short introduction of the calculation methodology is presented and the adopted basic assumptions are briefly explained. Through a trial-and-error type iterative procedure the magnitude of confining stresses and the confined strength of core material are determined, based on the compatibility of lateral deformations of the core column and the jacket-wall.
The accuracy of the proposed model for circular sections is demonstrated with a comparison with 149 test results.
