The purpose of this study was to investigate the characteristics of the rate of fatigue fracture propagation in members under maximum force on a steel arch bridge and to identify the fatigue life of those members under excessive loads. The method for bridge fatigue prediction used was numerical S-N curve controlled by cumulative damage rule, fracture critical member, and fatigue fracture determination based on SNI 1729-2015, S-N category. The distribution of stress, strain and life cycle was obtained. The result revealed 1 critical built-up weld beam on the steel arch bridge, specifically double welded wide flange beam TB7. Excessive loads from heavy vehicles, namely trailer types 7C1, 7C2 and 7C3, were simulated. Initial fracturing would occur after 53 years and 5 months of service with an initial crack size of 1.717 mm, leading to a propagation cycle of 45 years, which would cause critical fractures of 10.55 mm after 99 years. Thus, the maximum number of vehicles permitted to enter the bridge, assuming a 5% increase per year, was 13,450 per year for trailer type 7C3 at a planned capacity of 6,984,000 vehicles. This paper illustrates how fatigue life prediction can be a useful guide for the sustainability of bridges and provide a theoretical basis for developing optimized fatigue life of steel arch bridges.

Due to of its inherent strength and durability, wood is a valuable and abundant natural resource that is frequently used in the construction industry, road infrastructure, and bridge architecture. Notably, Galam Wood stands out as a distinct possibility for construction applications, as it may be used in its natural state without the need for specialist treatments. The current research digs into an examination of several areas of Galam Wood, including the bottom, middle, and higher regions. This inquiry integrates distinct ratios (1, 2, 3, 4, and 5) to investigate their respective influences on the material's strength. The chosen diameter of the specimens, varying between 5 cm and 10 cm, emerges as a critical element impacting compressive strength. In the size conditions of 10 cm diameter specimens, differences in section reveal a minimal influence on compressive strength, contrasting significantly with the considerable effect reported in the 5 cm diameter test items. The observable dissimilarity in compressive strength readings for the 10 cm diameter specimens remains below the threshold of 10%. Nevertheless, the careful selection of diverse ratios distinctly modifies the compressive strength outputs, underlining the critical function of this parameter in the behavior of Galam Wood under compressive loads.

In order to enhance the utilization of concrete, it is necessary to explore the impact of PVC pipes incorporated into hollow prism concrete, focusing on their effects on compressive strength and cracking. PVC pipes are commonly employed as reinforcements within concrete structures to bolster their stability. This research delves into the consequences of varying pipe diameters and PVC pipes within hollow prism concrete. The experimental process entails utilizing concrete prisms with 100 x 100 x 300 mm³ dimensions, possessing a compressive strength of 25 MPa. Research outcomes reveal that pipe diameter directly influences compressive strength, where larger diameters are associated with reduced compressive strength. Including pipes in the concrete does not yield a substantial discrepancy in compressive strength. Concrete prisms with incorporated pipes exhibit a Columnar-type collapse, indicative of dominant compressive stress, whereas prisms without pipes undergo a Shear-type collapse, signifying a shift in stress distribution. It emphasizes the pivotal role of reinforcements like PVC pipes in upholding the structural integrity of concrete, thereby mitigating potential damage.In order to enhance the utilization of concrete, it is necessary to explore the impact of PVC pipes incorporated into hollow prism concrete, focusing on their effects on compressive strength and cracking.

Weighbridges play a vital role in coal mining operations. This study aims to calculate the stress range and fatigue life of steel bridge girder cross-sections. Using the numerical simulation method with the CSI Bridge v22 application, the maximum axial force of 197 kN and the minimum axial force of -74 kN were obtained. The axial force is determined from the first 3 spans of the bridge with a span length of 4 m. The span length of the weighbridge is 80 m. From the calculation, the maximum stress of 40.11 MPa and the minimum stress of -15.06 MPa were obtained, resulting in a stress range of 55.16 MPa. The nominal bending moment strength of the beam was found to be 0.56. This modeling allows the simulation of dynamic loads from a 400-tonne SDT truck (semi-trailer door tipper) passing over the bridge so that accurate stress range data can be obtained. Fatigue analysis was carried out using the Basquin equation using the constant C = 1x1012 and exponent m = 3, receiving a fatigue life of 0.006 (6.01x106) cycles assuming 30-40 hauling trucks passing over the weighbridge. The results of calculations and simulations obtained longitudinal and transverse profile dimensions of IWF 1000x520x18x31.

Bridge reinforcement with external prestressing method is a proven effective approach to overcome damage in strengthening bridge structures. This method uses the installation of prestressing cables outside the steel frame of the bridge to increase the strength and stability of the structure. The bridge structure is made with the guidelines of SNI 1725: 2016 standard steel frame of class A bridges, using IWF and H Beam steel, with a plate thickness of 20 mm with a span length of 60 meters, a width of 9.13 meters and a height of 6.3 meters. The structural analysis of this study uses the SAP2000 v22 software program. In this study, 3 prestressing cable tensions were compared on the reinforcement of the bridge frame with the external prestressing method. And a loading simulation was carried out which could provide a response in the form of strain due to moving loads and a bridge structure response that was reduced by approximately 50% from the deflection force on the steel frame reference bridge if given a moving load. Choosing a bridge that has the lowest settlement. The review point is determined for the comparison of deflection at point object 7 and joint object U3. The Type E cable-stayed bridge has the lowest results in percentage, about 46.68% for a speed of 40 km/h, 48.60% for a vehicle speed of 50 km/h and 49.91% for a vehicle speed of 60 km/h, indicating that this bridge has the best analysis performance among the cable-stayed bridges analyzed.

The Samarinda Tunnel construction project is a strategic effort to support infrastructure development in East Kalimantan. This tunnel is located from Jalan Sultan Alimuddin, Sambutan District to Jalan Kakap, Samarinda Ilir District, with a length of 690 meters from the entrance (Inlet) to the exit (Outlet). This tunnel is expected to be able to reduce traffic jams that often occur on Jalan Otto Iskandar Dinata, Sungai Dama Village. This project is owned by the Samarinda City Government (PUPR) and is implemented by the contractor PT. PP Persero with PT. Ciria Jasa Cipta Mandiri is the supervising consultant. The construction method used is the New Austrian Tunneling Method (NATM), with a focus on the use of shotcrete and rockbolt to maintain the stability of the tunnel structure during and after the construction process. Shotcrete provides temporary protection against ground pressure, while rockbolt strengthens the rock mass around the tunnel. In this community service, observations were carried out using a participatory method, where observers were directly involved in the activities being observed. This approach allows for a deeper understanding of the application of shotcrete and rockbolts, as well as the effectiveness of the supervision carried out to ensure compliance with applicable technical specifications and standards.

The Sebulu Bridge Construction Project in Kutai Kartanegara Regency, East Kalimantan, aims to enhance interregional connectivity and facilitate the mobility of people and logistics distribution. This community service activity has two main objectives: to understand the methods of implementing Occupational Health and Safety (OHS) in the construction project, and to identify potential hazards that may cause work accidents through a hazard identification approach. The methods used in this activity include direct field observation, interviews with project implementers, and hazard analysis based on the types of work performed. The results indicate that the highest risks originate from working at heights, operating heavy equipment, and exposure to hazardous materials. OHS implementation measures include using personal protective equipment (PPE), periodic safety training, and intensive supervision at the project site. The discussion reveals that while the implementation of OHS has been relatively effective, there are still challenges related to worker discipline and limited supervisory resources. Therefore, increased supervision, stricter enforcement of OHS regulations, and regular evaluations are required to improve the effectiveness of safety systems on site.
