ANALISA KUAT TEKAN TERHADAP VARIASI BEBAN PEMODELAN DINDING CANTILEVER MENGGUNAKAN SAP 2000

Abstract

The construction of a retaining wall that is classified as simple is necessary to consider the model, analysis of the material, and the calculation of the avalanche that will fall on the retaining wall. This study used the modelling method of retaining wall with the calculation method of SAP 2000. This wall modelling used a Cantilever type wall with a height of 550 cm and a width of 385 cm. This modelling is useful to calculate the minimum strength of the cantilever wall for retaining the soil at the Balerejo Kalegen road. Further, this wall was modelled to have a width of 55 cm, a heel width of 130 cm, a foot width of 130 cm, the following foot width of 100 cm, with a wall that was embedded with a depth of 50 cm and used evenly distributed load variations, which has been adjusted where the load used were 11.138, 5.5, 0.3869 tons. When inputting data into SAP 2000 beforehand, calculations must be made related to the force that will affect the wall, followed by wall modelling according to the Cantilever shape. Subsequently, the compressive and shear strength of the Cantilever wall that has been made can be calculated where the compressive strength produced of the front wall has an average of 175.154 tons m; that of the back has an average of 62.666 tons m; that of the front heel has an average of 866.054 tons m, and that of the back heel has an average of 910.463 tons m. Based on the data and analysis of the design of the soil retaining wall in the Balarejo road section, the average compressive strength for the front wall is 175.154 tons m. It shows that the soil retainer is very good compared to the pressure from the soil that will be received.
