Abstract

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.

Abstract

Concrete, known for its high compressive strength and resistance to environmental degradation, proves ideal for durable building construction if implemented correctly. Mix designers, implementers, and supervisors must comprehend concrete properties to prevent errors in construction. Vibrators play a crucial role in enhancing concrete quality and strength during casting, facilitating air removal, ensuring even distribution, and increasing density. This research evaluates the impact of vibrators on mechanical properties and strength, utilizing a hammer test to compare unconfined compressive strength in samples cast with and without vibrators. Results indicate that vibrators significantly enhance concrete compactness, reduce cracking risk, and improve pressure resistance. Additionally, they positively influence aggregate distribution and reduce porosity. Integrating vibrators into the casting process is essential, offering tangible benefits for structural performance and building durability. Practical implications include guidance on optimal vibrator use in construction projects for superior outcomes. Concrete damage poses a common challenge in construction, affecting elements like columns, beams, plates, and walls. Conducting case studies on damage causes is crucial to identify and minimize potential issues, ensuring the long-term integrity of structures.

Abstract

This study investigated volumetric analysis on asphalt concrete mixtures containing fly ash filler and glass powder waste filler, focusing on the response to local inundation of seawater. This study investigated volumetric analysis on asphalt concrete mixtures containing fly ash filler and glass powder waste filler, focusing on response to local inundation of seawater which includes Stability, Flow, VIM, VMA, and VFB. In the 4-day seawater puddle model cycle, 12 specimens were made: 3 fly ash fillers, 3 glass powder waste fillers, and 3 normal asphalt, tested for 5 hours and 10 hours. This study explores the impact of fillers and inundation cycles on asphalt concrete characteristics. To realize the model of seawater puddles, in cylindrical specimens PVC retaining rings of the same diameter as the specimen (100 mm) are used tightly covered with silicone on the specimen surface. Filler with glass powder has low hygroscopic properties, which can help reduce moisture absorption in asphalt mixture beyond filler with fly ash. This can reduce the risk of changes in mechanical properties due to high water content. This study can provide an analysis of how well the asphalt mixture is able to withstand moisture and the extent to which glass powder filler and fly ash filler affect the absorbency of the mixture.

Abstract

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.

Abstract

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.
