Abstract

Precast system is one of the reinforced concrete construction methods that can be used for development. GFRP-S (Glass Fiber Reinforced Polymer Sheet) is one of material that can be used as materials in precast concrete connections. The research aimed at analysing the strenght and behaviour of the concrete beams on beam-column joint precast with GFRP-S.The research was conducted at the Laboratory of Civil Engineering Structures and Materials Hasanuddin University. Beams dimensions was 15cm x 20cm x 120cm and the column was 45cm x 20cm x 100cm. The testing materials were the precast beams with GFRP-S. The imposition given is monotonic static load in one direction.The results showed that an increase in stiffness of the precast beams with GFRP-S. LSI amounted to 16.64% of the LS. LIS amounted to 31.70% of the LS. The average deflection of LS are 55.05 mm. The average deflection of LSI are 45.89 mm. The average deflection of LIS are 37.60 mm. The models of failure in the precast beams with GFRP-S are rupture failure of GFRP-S.

Abstract

After a strong earthquake with a magnitude of 7.4 on the Richter Scale with a hypocenter of 10 km and an epicenter of about 70 km north of Palu City, precisely in Lende Village, Sirenja District, Donggala Regency, it caused damage and collapse of buildings due to vibrations, fractures of down lifts and up lifts around the fault trajectory. Palu-Koro. Damage and failure of high-rise and non-rise buildings occurred in Palu City, Donggala City, and Parigi City. Damage to the building can be categorized as light, moderate or heavy damage, so it is deemed necessary to conduct an assessment according to the applicable requirements both on a national scale (using the Ministry of Public Works and Public Housing's 2010 form) and an international form (using a form from the World Bank). This activity aims to determine the level of damage and post-earthquake handling in the form of minor repairs, reinforcement and repair of structural and non-structural elements. There are 6 (six) main buildings in the 3 (three) areas that have been assessed to determine the category of damage and actions for rehabilitation and reconstruction. Damage to the building structure with the category of Light Damage occurred in the Palu City DPRD Office building, the Donggala Regent and DPRD Office and the Anuntaloko Parigi Hospital Inpatient Building. Those that were moderately damaged were the Palu Mayor's Office building and the Parigi Moutong DPRD office. The damaged buildings still allow for repairs and reinforcement according to the level of damage. The repair and strengthening of buildings in order to get good results must be carried out with the right method, good materials and tools and technology and carried out by experienced workers with high qualifications

Abstract

The bridge reconstruction project is an effort to rebuild bridges that have been destroyed by the earthquake and tsunami that hit Palu City. The implementation of the bridge reconstruction project has complicated work that raises an analysis of the effect of the bridge project implementation method on project time performance. The purpose of this study was to determine the effect of implementation methods on the time performance of the bridge reconstruction project in Palu City. The sample of this study amounted to 22 workers on the bridge reconstruction project using Purposive Sampling method. The field collection process was carried out by collecting primary data in the form of interviews and distributing questionnaires. The data were processed using descriptive statistics and multiple linear regression analysis. The results of this study indicate that partially of the five variabels affecting the implementation method, the material factor variabel has a significant effect on the time performance of the bridge reconstruction project. While simultaneously work methods, labor, material factors, equipment, and project site conditions have an effect of 8,988 with a significant 0.000 on the variabel time performance of the bridge reconstruction project in Palu City.
