Strengthening reinforced concrete T connections by steel straps
The aim of this paper is to present results of testing a full scale reinforced concrete T connection by static loading. The connection is a T connection representing a beam-column connection. The beam and column had a square cross section with a 300 mm dimension. The height of the column was 2.9 m and the clear beam length was 1.4 m. The connection was initially tested to failure. Galvanised st...
متن کاملComputer-Aided Strengthening of Steel and Reinforced Concrete Telecommunication Poles
ABSTRACT: The absence of explicit guidelines for the rehabilitation of existing pole structures was the motivation to investigate the effectiveness of steel jacketing for the retrofitting of self-supporting steel and reinforced concrete telecommunication poles. The present study describes a numerical simulation of preand post-retrofitted conditions of the pole structures subjected to seismic ha...
متن کاملSeismic Design of Concrete-Filled Circular Steel Bridge Piers
The adequacy of the existing design provisions for concrete-filled steel pipes subjected to axial forces and flexure is reviewed by comparing the strengths predicted by the CAN/CSA-S16.1-M94, AISC LRFD 1994, and the Eurocode 4 1994 codes and standards against experimental data from a number of investigators. New proposed design equations are then developed, in a format compatible with North Ame...
متن کاملStrengthening of Scaled Steel-Concrete Composite Girders and Steel Monopole Towers with CFRP
Cost-effective rehabilitation and/or strengthening of steel structures currently demanded by the telecommunications industry and transportation departments. Rehabilitation is often required due to crosssection losses resulting from corrosion damage and strengthening may be required due to changes in the use of a structure. Current strengthening techniques, have several disadvantages including t...
متن کاملA Robotic System for Steel Bridge Maintenance: Field Testing
This paper presents the field testing results of an autonomous manipulator-based robotic system that strips the paint and rust from steel bridges [Liu et al., 2008]. The key components of this system are sensing and planning, which have been presented in other research papers. The grit-blasting field trial presented in this paper spanned 6 weeks, and included 20 hours over 4.5 days of actual gr...
