Concrete structures can be damaged or deteriorate due to various reasons such as errors in planning, implementation factors, getting overload burden, decreased capacity and quality of structures, and changes in structural functions. Thus, to strengthen the damaged structures, there is a need for an investigation regarding the damage to the existing concrete structures. Retrofitting FRP (Fiber Reinforced Polymer) to the damaged structures can be a reinforcement alternative. The bond shear between FRP and concrete need to be considered in using FRP to solve the damaged structure. Shear behavior on the bonded structures greatly affects the condition of the structure. Therefore, this study aimed to examine the effect of anchors and stakes on FRP debonding behavior. This study was carried out experimentally to obtain the results and data on the effects of the anchors and stakes. This study used 9 specimens with a size of 150 mm x 150 mm x 300 mm. From those 9 specimens, 3 specimens were specimens without reinforcement (FR), 3 specimens were reinforced with anchor (FRA), and 3 specimens were reinforced with anchor and stake (FRAP). The test method used in this study referred to ASTM D5379 concerning the Standard Test Method for Shear Properties of Composite Materials. From the bond shear test of each FR, FRA, and FRAP specimens, it was found that the average maximum shear load was 19.405 kN, 28.465 kN, and 29.699 kN, consecutively.

Most parts of Indonesia are earthquake prone areas with medium and high intensity. In the process of constructing the building, it needs to pay attention to several aspects. One of it is the effect of the earthquake. Earthquakes always attack the joint structure so that the structure needs to be designed using the moment-bearing frame system method with the concept of strong columns and weak beams combined with shear walls, so that the building can muffle earthquake vibrations. The building of Lidra Hotel, located on Raya Sedau Street, Samudera Indah beach, Sungai Raya Kepulauan sub-District, Bengkayang Regency, West Kalimantan Province. The building consists of 17 floors with a height of 67 meters from the ground, reinforced concrete structure. Based on the results of the Standard Penetration Test, this building will be builded on medium ground (SD site class) and included in the Seismic Design Category (KDS) D, then the calculation of this building uses the Special Moment Resistant Frame System (SRPMK) combined with a shear wall, so it is called the Dual System Method. Earthquake load planning uses the 2017 Indonesia Earthquake Map using the spectrum response method according to SNI 1726-2019. Calculation of loading according to SNI 1727-2020 and PPPURG 1987, structural concrete requirements for buildings according to SNI 2847-2019, calculation of structural steel roof according to SNI 1729-2020. Based on the calculation of the roof some results were obtained the size of the column and the truss size IWF 148.100.6.9mm, CNP gording 150.50.20.3,2mm, 1 type of plate 130mm; 2 types of beams 350mm/700mm and 300mm/600mm; 4 types of columns, K1 1200mm x 600mm, K2 800mm x 800mm K3 1000mm x 500mm, and K4 700mm x 700mm; 1 type of shear wall 300mm; ladder plate and balustrade 130mm; 4 types of foundation 3600mm x 3600mm x 700mm – spun pile 9 D 600mm; 1500mm x 1500mm x 400mm – spun pile 4 D 350mm; 3000mm x 3000mm x 500mm – spun pile 9 D 500mm; 7600mm x 5600mm x 1000mm – spun pile 12 – 800mm. Keywords: Building Structure, Earthquake Resistance, Dual System, Spectrum Response.

The purpose of this research is to arrange the stages of implementation of the ABILA precast concrete construction method to be applied to housing construction so that it can be used as a reference for future development. While the purpose of this research is to arrange the stages of housing construction with ABILA precast panels starting from the precast concrete production stage, transportation or mobilization of materials to the installation process and final completion. Precast concrete can speed up processing time, save costs, and minimize waste for formwork and scaffolding. In the world of construction, any waste of construction material must be reduced or even eliminated. The application of Precast Concrete is very easy, considering its plug and play nature. Besides being easy, precast concrete has quite a lot of applications, especially the Abila Panel which has a function as a building structure, it can also be used as fences, floors and drainage channels. The level of the implementation method for the development of precast concrete technology is divided into several levels between prefabrication, preassembly, and module. The implementation method of building a house with ABILA precast concrete takes 14 days in the field, starting from panel installation to finishing. The construction method includes prefabrication in the workshop, mobilization of panels to the job site, assembly of structural elements, installation of brick walls, installation of roof structures and roof coverings, electrical and mechanical floor work, installation of ventilation doors and windows and paint finishing.

The Melawi Regency Public Service Mall Building is planned in West Kalimantan which is an area with low earthquake intensity. Every building structure in Indonesia needs to be planned to withstand earthquakes. The planned structural elements such as plates, beams, columns, and foundations must have sufficient strength to withstand earthquake loads in order to provide a sense of security for the occupants of the building. Structural planning uses reinforced concrete material according to SNI 2847-2019. The material quality used is concrete fc' 25 Mpa and 30 Mpa, reinforcement fy 420 Mpa and fy 280 Mpa. Structural loading refers to PPPURG 1987 and SNI 1727-2020. Earthquake load analysis uses the spectrum response method which refers to SNI 1726-2019. Modeling and structural analysis using the SAP2000 program. The results of determining the structural system obtained for the Public Service Mall building structure use the Ordinary Moment Bearing Frame System (SRPMB) as a seismic force resisting system. The calculation results obtained a 12 cm plate for the floor, 13 cm for the roof deck, 15 cm for the elevator pit, 20 cm for the stairs with D10 reinforcement. Dimension of main beam and bordes 30/50 cm, subsidiary beam and elevator 25/40 cm with D16 reinforcement. Column dimension 50/50 cm with 12D19 reinforcement. The foundation uses a pilecape measuring 150x150x50 cm with 4 piles with a diameter of 30/30 cm 14 m deep
