Abstract

Overloading of structures can cause failure. In order to continue using them, strengthening is required. In this research elastic strengthening was carried out on concrete floor plates by means of tensile reinforcement addition, and mortar composite additionto apply epoxy resin. Four reinforced concrete slabs, consisted of one control slab (PK), one monolith slab (PM), one strengthened slab (PPE) and one unstrengthened slab (PPTE). Specimen dimensions were 700 mm x 1500 mm x 60 mm for the PK, and 700 mm x 1500 mm x 100 mm for the others. Specimens were placed on a simply supported loading frame, and statically loaded at their mid-span. Numerical analysis using Response-2000 software package was carried out for comparison with the experiment al result. It was found out that the flexural capacity of the PK, PPE, PPTE and PM specimens are 5,99 kNm, 12,52 kNm, 13,87 kNm and 21,38 kNm, respectively. In comparison with that of thePK, flexural capacity of the PPE and PPTE specimens was found to increase by 109,019 % and 131,55 %, respectively. The increase of stiffness was 324,77 % and 430,21 % for the PPE and PPTE specimens, respectively. The ductility factor of the PPE and PPTE increase 29,63 % and 19,03 %, respectively . The PK and PM specimen s experienced flexural failure, while the PPE and PPTE specimens experienced debondingfailure.

Abstract

The lap splice method presents a drawback due to reinforcement congestion, affecting the pouring and evenness of the concrete. Additionally, lap splicing significantly contributes to construction waste. As a result, research was conducted on mechanical connections using reinforcements to reduce construction waste and demonstrate the feasibility of these splices. In this study, the threaded coupler with standard national coarse threads splice method was employed, and tests were conducted following ASTM A1034-10a standards with monotonic tensile loading. Test specimens were created using 13 and 16 mm reinforcement sizes, varying the length and diameter of the coupler, and including welding at the coupler ends. The test results demonstrated that reinforced bars with splices exhibit a stress-strain relationship similar to intact reinforcement. However, these reinforced bars with splices did not meet the requirements outlined in SNI 2052:2017 concerning maximum stress and strain, including their comparison. Therefore, the utilization of these splices is not suitable for critical load-bearing areas.
