Abstract

Prestressed concrete is the perfect composite consisting of high-strength concrete and strands with reinforcement with high yield strength Prestressed concrete beam is one of the concrete innovations that have been used in many constructions. The advantage of prestressed concrete particularly using the post-tensioning method, in designing and applying prestressed concrete beam for the building is that the tensioning can be carried out in stages, for all tendons in a member, or some of them Prestressed concrete beam using post-tensioning method can be an alternative to increase the span of the building when removing the existing column in the center of the building is required. In this paper, the use of prestressed concrete beam will be designed in Nyitdah Hospital-Tabanan, Bali. The prestressed beam is designed with 60/90 cm dimension and 1 tendon unit with 12 strands unit. Based on the design and result, the prestressed beam can be used as the alternative to increase spans in a building room of the Nyitdah hospital.

Abstract

This study focuses on strengthening scheme of an existing structure with added story. The addition of a new story increases gravitational loading, which affects the seismic and wind responses of the structure and, as a consequence, the loading combination. To ensure the structure’s capacity requirement, the strengthening scheme uses CFRP (Carbon Fiber Reinforced Polymer). In order to adequately define the structure's performance, a series of structural analyses were performed. The structure's state before and after story addition, subsequently the state after CFRP strengthening, were evaluated. It is demonstrated that the additional story to the structure causes an exceedance in internal forces; however, the strengthening with CFRP is sufficient to withstand these forces, proving that the strengthening scheme is effective and beneficial.

Abstract

This study focuses on the design implementation and performance analysis of concrete-steel composite structure of a four-story Kutus-Kutus Factory, a facility for the production of herbal oils, built in the seismically active Gianyar district of Bali. In order to create an efficient, fully composite cross section, the design process uses an analytical approach that emphasizes the relationship between the concrete slab and steel beams as well as the design of each of these components. The structure was designed and assessed in accordance with Indonesia Building Standard guidelines for minimum load, earthquake-resistant, and concrete and steel based material requirements. The final results of the design confirmed that the composite performance is strong enough to withstand enormous loads combined in industrial buildings, particularly in seismically active areas, and can operate within the recommended safety margins and restrictions. This paper ends with a call for more research on the real application of composite structure design in Indonesia, which can then assist the rapidly expanding Indonesian construction industry in maximizing the advantages of using composite construction techniques.

Abstract

Sukawati Market Building has 4 floors and 1 basement with a total building area of 1136.16 m2. It was designed to use a flat slab structure system with the addition of drop panels that maintained the height or story clearance while reducing total building height by eliminating the interior beams. The structure was designed follow the Indonesian Standard for reinforced concrete building design guideline and assessed through finite element simulation. The shear capacity of the flat slab was determined by the strength of the concrete and its dimensions. The reinforcing bar of flat slabs with drop panels is determined in the same way as the reinforcing bar of concrete slabs. Based on the results, the design efficiently resists the forces demand while meeting the deflection requirement, reflecting the structure system's safety and serviceability. The structure system also maintains the total height of the building in order to comply with local high-limit regulation.

Abstract

The development of earthquake-resistant building designs led to developing an analysis method for earthquake loads, one of the performance-based methods. This method uses structural displacement as an approach. The purpose of this analysis method was to guarantee the structure's performance so that it will be able to withstand forces due to earthquake loads. In this paper, an analysis of a building structure's design was more reliable with applicable regulations in Indonesia and determined building performance based on FEMA 356. The study was carried out using the direct displacement method and the pushover analysis method, with the displacement targets and structure performance levels being compared with each other. Based on these results, it can conclude that the use of the direct displacement method and pushover analysis can produce almost the same displacement target values and structure performance levels. Comparison using pushover analysis design performance targets can be fulfilled so that the Direct Displacement Based Design Method can be used in structures. The total displacement value of the x-x (δT) direction is 0.300 m, and the y-y course is 0.115 m.

Abstract

Infrastruktur berperan penting mengoneksikan antar daerah termasuk pusat ekonomi dengan kawasan sekitarnya. Pemerintah telah menggelontorkan 2T untuk KEK Labuan Bajo meliputi 3A (Atraksi, Aksesibilitas, Amenitas) Seperti penataan TNK, penataan DTW Budaya di desa Liang Ndara, penataan kawasan Batu Cermin. Kementrian Lingkungan Hidup dan Kehutanan Republik Indonesia mempunyai program nasional untuk memenuhi kebutuhan kayu dalam negeri dengan 1.000 kebun bibit dan 51 persemaian modern di seluruh Indonesia. Desa Nggorang ditetapkan pemerintah sebagai tempat Persemaian Modern dengan luas lahan 30 Hektar. Desa Nggorang memiliki potensi dan Infrastruktur yang ada tergolong cukup baik namum infrastruktur di Persemaian Modern belum memadai dan memerlukan penataan. Langkah awal dalam pengembangan Kawasan persemaian modern sebagai salah satu destinasi yang berbasis ekowisata, diusulkan adanya beberapa infrastruktur dan sarana pendukung seperti bangunan Loby, pusat souvenir, gazebo dan jogging track yang berada di jalur utama Kawasan persemaian modern. Bangunan loby terletak dekat dengan main entrance dari Kawasan persemaian modern dengan adopsi model bangunan Suku Manggarai yaitu Mbaru Niang. Bangunan pusat souvenir diletakan bersebelahan dengan bangunan loby, konsep bangunannya diadopsi dari tipologi rumah suku Bajo. Untuk Jalur jogging track akan melintasi jalur utama di Kawasan persemaian modern. Panjang jalur jogging track adalah 1500 meter. Di beberapa titik sepanjang jalur jogging track disediakan gazebo yang digunakan sebagai tempat istirahat sementara. Konsep tempat peristirahatan (rest area) adalah Gazebo dengan atap alang-alang dengan struktur kayu untuk menimbulkan kesan natural dan menyatu dengan alam yang ada di Kawasan persemaian modern.

Abstract

The absence of an assessment of the level of damage and the condition of the Bali Mandara Hospital building makes the maintenance management plan contained in the umbrella contract only based on the damage that occurred in the previous year. Therefore, it is very difficult to determine which building infrastructure components require maintenance and repair first. This study examines the priority scale of infrastructure maintenance at Bali Mandara Hospital using the Analytical Hierarchy Process (AHP). In this study, researchers used a quantitative-descriptive approach. The assessment of the building condition index value is then determined by the priority scale of each component using the Analytical Hierarchy Process (AHP) method with the help of the Expert Choice Version 11 application and the SWOT Method. The results showed that the index value for the infrastructure condition of the Bali Mandara Hospital building was 89.492 with very good condition criteria and was in zone I, while the highest priority scale was faucets, namely 1,000, and the lowest priority was action on a scale of 0.050, where this priority scale can be used in planning. Standard Operating Procedure (SOP) and efficient maintenance management. So based on the results of this study, with SWOT analysis, maintenance management can develop a more effective and efficient maintenance plan and Standard Operating Procedure (SOP) by the building condition index and existing priority scale.
