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

This study examines the seismic vulnerability of an irregular educational building with a vegetated roof in Yogyakarta using linear procedures based on ASCE 41-17. Modelling approaches differ Model 1 treats skylights and planter boxes as loads with straight roof slabs, while Models 2 and 3 use shells with sloping roof slabs. Vegetated roofs are featured in Models 1 and 2. The analysis, conducted at seismic hazard levels BSE-1N and BSE-2N using the ETABS program, evaluates structural components and compares Response Spectrum (RS) and Linear Time History (LTH) methods. Results show seismic weight variations of 1.20% to 15.04% between models. Model 1 fails to meet the criteria for modal analysis, while Models 2 and 3 do. The structural performance evaluation based on average demands at BSE-1N and BSE-2N levels varied from Immediate Occupancy to Life Safety performance. The LTH method in all models had higher acceptance ratios than the RS method.
