Abstract

The strength of the anchor block structure in the suspension bridge is very dependent on its weight to be able to bear the tensile load of the backstay cable. Therefore, it is necessary to have dimensions large enough to withstand the tensile force. Concrete has good compressive strength but does not have good tensile strength, the tensile strength of concrete is only about 10%-15% of its compressive strength. Therefore, in planning anchor blocks, anchor blocks are needed making of steel that has high yield and fracture stresses and is planted in anchor concrete blocks to withstand the force before the tensile stresses are transferred to the concrete blocks. In this paper, steel H 300.300.10.15 is used as steel anchors embedded in concrete blocks. The purpose of this study was to obtain the stress value that occurs in the anchor block using the Ansys assistance program, obtain the appropriate reinforcement distance in the maximum tensile area (critical area), and obtain a graphic description of the influence of the anchor structure geometry due to the load from the backstay cable. This research was conducted using a numerical study using the SAP 2000 assistance program to calculate the forces in the entire suspension bridge structure, then using the Ansys analysis assistance program to obtain the tensile stress that occurs in the anchor block which is also modeled in Ansys with boundary conditions that are close to the existing conditions in the field. The results of Ansys analysis show that the maximum tensile stress in H profile steel 300.300.10.15 is 73.27 MPa and the maximum tensile stress in concrete is 1.26 MPa. The value of 1.26 MPa is still within a safe limit because the tensile stress is still below the allowable tensile stress for the concrete of 2.23 MPa. From the results of empirical analysis, the maximum reinforcement space in the critical area is 150 mm, and in the non-critical area, it is 250 mm.

Abstract

The condition of road pavement is going to decrease during its service life. To keep a pavement functioning, maintenance must be continuously performed. However, the maintenance that has been carried out so far has not been carried out optimally because the budgeting system is still carried out annually based on the results of a road condition survey. The preparation of the budget is carried out annually by BBPJN SUMUT as the relevant stake holder, based on the FWD value with a back calculation program. This causes funding to become unsustainable so that it affects unsustainable handling as well. There are several methods for calculating predictions of future damage values ​​including IRMS-V3 and RONET. Both have a basis for calculating the value of IRI as the main variable in predicting damage. The purpose of this study is to use both methods and compare them to predict IRI values, traffic growth values, and also the remaining planned life values ​​in order to obtain a funding/budget planning scheme and the right type of treatment. The type of data used is secondary data sourced from North Sumatra BBPJN. The analysis is carried out by calculating the IRI value, traffic volume, and the remaining planned life for the next 5 years. Based on the results of the analysis obtained, road damage will occur more quickly using the RONET method. Road maintenance funds resulting from the IRMS-V3 method are more economical. Then validated using statistical t test. The results show that there is no difference in the average predicted IRI value, but there is a difference in the average predicted RSL value for the two methods
