<![CDATA[The Kadungora-Leles alternative road fly over bridge is the first bridge in Garut Regency to use steel box girders as its girders. Therefore, the author is interested in conducting an analysis of the steel box girder structure on this bridge. The method used in the analysis of this bridge girder structure is the Allowable Stress Design method. This analysis assumes that the stress that occurs due to the service load, which is calculated based on the elastic theory of bending beams, does not exceed the specified allowable stress. Permissible stress is determined as the ultimate strength or yield strength of steel divided by the safety factor. Bridge loading refers to SNI 1725:2016, while for analysis of bolted connections using RSNI T-03-2005. From the analysis results, it was found that the steel box girder bridge girder structure experienced a tensile stress of 1801.41 kg/cm2, experienced a deflection of 101.991 mm. After analyzing the girder connections, it was found that the bottom flange connection plate has a shear-yield capacity of 9135000 N, the web connection plate has a shear-yield capacity of 9020160 N. The bottom flange connection plate has a total of 72 bolts (24 mm) , whereas according to the analysis results only 31 bolts are needed. The bolt configuration on the web connection plate has a shear capacity of 11928.992 kN, while the shear force that must be supported is 421.933 Kn.]]>

<![CDATA[The concept of earthquake resistant buildings is based on the yield mechanism in one element. In the steel frame structure core system, the coupling beam functions as an earthquake energy dissipation element where yielding is planned. However, if these elements are damaged, repair costs will be high and the process will disrupt building activities. Considering these conditions, the coupling beam element was developed by adding a sliding link. The yield mechanism is transferred to the link element while the coupling beam remains elastic. Numerical and experimental studies were carried out to review the yielding behavior that occurs in the link and coupling beam elements. The sub-assembly consisting of the column, coupling beam and shear link WF150x75x6x8 was tested under cyclic loading in accordance with AISC 341-10. Numerical analysis is carried out using a pushover method where parameters related to the non-linear properties of each sub-assembly are designed based on the provisions of FEMA-356. The pushover and experimental analysis results show that yielding can be maintained in the link. Cyclic testing on the Sub-assembly produces plastic rotation of the shear link of 0.17 radians without causing damage to the column and coupling beam. The first yield in the pushover analysis occurred at a force of 180.9 kN, while the experimental results occurred at a loading of 157.04 kN. Cyclic testing shows an increase in shear capacity of 7% from the results of the pushover analysis.]]>

<![CDATA[One type of construction is building construction, an important infrastructure in human life and widely used throughout the world. Building construction can be used for various activities, such as residences, offices, shopping centers, and the like. Therefore, technology that can help make building plans easier and more connected is needed, namely calculating the analysis of the building structure using the finite element method (Finite.Element.Method). The evaluation calculation also refers to SNI`1726,1727, and 2847:2019. The load calculation includes wind, earthquake, dead and live loads. The upper and lower structures are the structural components that are analyzed. The results of the evaluation calculation show that the concrete structure is able to withstand the given loads, seen from the 600 x 600 dimension column where the moment acting on the column is 171 kNm while the moment that the column can withstand is 496.7 kNm with a ratio of 0.346 , so it can be said that the structure is very safe, but in terms of efficiency the material used in the column can be said to be wasteful.]]>

<![CDATA[The cross-sectional dimensions of wood are limited because they experience swelling and shrinkage, so to obtain large wood dimensions, one way to do this is lamination. Laminated wood beams are combined with reinforced concrete plates to produce a structural form where the wood is protected by a concrete plate. The wood lamination system in this research uses adhesive bolts with Carbon Fiber Reinforced Polymer (CFRP) as external reinforcement. The test beam consists of a normal beam without reinforcement (BLN-00) and a test beam with external reinforcement with a CFRP layer (BLF-01). This research was carried out experimentally using the Displacement Control method. The test beam was loaded with a monotonic static concentrated load in the middle of the span with a constant speed of 0.05 mm/s until failure. The results showed that the normal test beam without reinforcement (BLN-00) had a strength of 52.43 kN, stiffness of 7.06 kN/mm, and ductility of 13.42. Meanwhile, the beam with CFRP reinforcement (BLF-01) has a strength of 65.81 kN, stiffness of 9.33 kN/mm, and ductility of 16.85. Apart from that, the maximum shear stress value that occurs in normal beams is 4.23 MPa and in beams with CFRP reinforcement it is 1.95 MPa.]]>

<![CDATA[Clean water is the main source for society. However, not all areas have sufficient availability of clean water, for example Pangkalan Village and Pasir Mukti Village which are located in Tenjowaringin Village. In this research, planning for the availability of clean water was carried out for the people of Pangkalan village and Pasir Mukti village. The spring used in the planning was the Cipeuti spring, the water source of which had not been utilized at all. The method used to determine the amount of discharge is the volumethic method by collecting spring water, then the water is raised to the distribution reservoir using a pump, then the water is distributed using a gravity system. However, the method that will later be used for distribution of clean water is planned using the help of Epanet 2.2 software. The results of the analysis of water needs until the 2033 plan year showed that the population was 474 people using the geometric method, for a water discharge of 13,140 lt/day (0.16 lt/sec) with Cipeuti water availability until 2033, namely 0.17 lt/sec. The results of the calculations show that the availability of clean water in Cipeuti can meet the water needs of the people of Pangkalan village and Pasir Mukti village. For the dimensions of the reservoir used, namely 2.5 m x 2.5 m x 3 m and the dimensions of the planned reservoir are 2.5 m x 2.5 m x 3.5 m, the type of pipe used is HDPE pipe, where the value of the pipe coefficient uses Hazen Williams values ”‹”‹which will later be applied in the Epanet 2.2 application for pipe distribution.]]>
