Abstract

Columns are the most important element in a structure. Indonesian concrete regulations SNI 2847-2013 states that columns are elements that receive a minimum axial and bending loads of 0.1 Pu. Column damage can occur due to overloading damage, poor detailing in design, poor construction, etc. However, the most frequent damage is post-earthquake damage. The easiest reinforcement is the concrete jacketing method. The reinforcement material used in this research is bamboo. The test was done using the Quasi Static Loading Test method with lateral loads according to the displacement control and constant axial load. The results showed that the reinforcement by concrete jacketing from the initial dimensions of 15x15x90 cm to 21x21x90 cm showed the increase of lateral capacity, ductility, stiffness, and energy dissipation. In addition, it can be seen that the effect of reinforcement on both damaged and undamaged columns is less significant, which means that reinforcement can restore the initial capacity of existing test specimens to exceed 100%.

Abstract

This Abdimas activity in the form of Science and Technology for the Community (IbM) is a structural design consultation assistance for the GYS (True Jesus Church) building in Banjarmasin City, South Kalimantan Province. This building is a center for educational activities and a place of worship for the people of Banjarmasin City. This building will be built with 6 floors functionally. This community service activity has a specific purpose as an effort to provide technical assistance to the planning of earthquake-resistant high-rise buildings by applying building planning rules in accordance with the applicable SNI code. Another aim is to support development efforts that are oriented towards educational activities and also places of community worship. The plan of activities carried out is in the form of studying the description of the location of the abdimas (site survey), modeling structural analysis, interpreting the results and providing recommendations for the results.

Abstract

High-rise buildings in Indonesia must be designed resistance to receiving earthquakes. This is because the earthquake load that occurred in Indonesia has a high intensity. So that existing buildings, especially multi-story buildings must ensure good performance in receiving earthquake loads. This effort aims to maintain the safety of its users. Several aspects that need to be considered in designing earthquake-resistant buildings are structural performance and construction costs. Therefore, in this study, we will discuss the designed of earthquake-resistant structures by making comparisons on concrete structures and also steel structures which will then analyze the cost of the structure for the structures that have been analyzed and designed. From the results of the analysis, for the same conditions, earthquake resisting frame with reinforced concrete construction, it requires cheaper construction costs compared to steel construction. Concrete construction requires a structural cost of Rp. 19,030,188,114.0 and for a steel structure of Rp. 72,206,697,860.7. This is certainly not a conclusion that concrete construction is superior to steel construction. Because even though it is more expensive in terms of cost, steel construction is quite superior in terms of quality, time efficiency and ease of implementation.

Abstract

Malang city is one of the cities where the society is always increasing every year. This is because the city of Malang is one of the cities of education and also a tourist city where the nature is cool. With this, it is one of the reasons for building the Begawan Apartement Building in the city of Malang. The purpose of this planning study is to plan a safe and comfortable building structure for a high-rise building structure in the BEGAWAN LOWOKWARU apartment Malang. In order to minimize damage to the planning structure of a high-rise building during an earthquake, it is necessary to take into account all possible working loads. In planning the Begawan Lowokwaru Malang Partemen Building,Bearer it was designed to use a special MomentFrame System (SRPMK). In this structural planning, the auxiliary program is used, namely ETABS V.16.2.0 with reference to the SNI 03-1726-2019 regulations concerning the procedures for Earthquake resistance planning for Building and Non-Building Structures, as well as SNI 03-2847-2013 concerning Structural Concrete Requirements for Buildings. Building. Based on the analysis results of this final project, it is found that the beam and column structural design is capable so that the design of the strong column weak beam "Strong Column Weak Beam" ΣMnc ≥ 1.2 ΣMnb is obtained with the detailing of the beam column relationship that meets the requirements of SNI 2847-2013.

Abstract

The increasing demand for concrete as a construction material has resulted in the depletion of natural resources. This motivates the construction industry to continue to innovate in the manufacture of concrete. The utilization of iron ore waste as a substitute for fine aggregate is one of the solutions. This study aims to determine the optimum composition of iron ore waste as a substitute for fine aggregate on compressive test strength and economic value of concrete mix materials. This study used coarse aggregate from the quarry location of Mount Batu PTP Pelaihari District, Tanah Laut Regency, fine aggregate from the iron ore crushing plant location from the stockpile of Perusda Baratala and ex. Palangkaraya. The testing at the UPT Construction Material Testing Laboratory DPUPRP Tanah Laut Regency, South Kalimantan Province. The results showed that concrete using fine aggregate/sand ex. Palangkaraya has a concrete quality of K-235.94 kg/cm2 or fc'= 19.583 Mpa. As a result, it was found that the concrete mixes were more efficient than the concrete mixes used in the concrete batching plant, and that the concrete mixes were more efficient than the concrete mixes used in the concrete batching plant AK (Coarse aggregat) 54%: AH (fine aggregates) 45% has a concrete quality of K-257.29 kg/cm2 or fc'= 22.849 Mpa. This shows that iron ore waste fine aggregate can be used in concrete mixes
