Abstract

Before the development of the framework structure (using beams and columns), loadbearing wall structure with loads that will work on the building structure bestowed on the walls commonly used in the community. One form loadbearing wall structure is commonly used arrangement brick wall. Adobe is a brick made by printing and maintaining in a damp atmosphere, tras mix, lime and water with or without other additives. One brick technology that has been developed is the use of brick without plaster and adhesives. The composition brick wall has a good ability in resisting axial forces but weak in resisting lateral forces. One of the solutions used to improve the ability of the composition of the brick wall is the lateral force resist giving the initial prestressing force (prestressed) through fastening reinforcement (via tightening bolts). Prediction failure of brick wall composition into focus the problem in this research. Experimental testing in the laboratory, carried out to see the damage that occurs in the form of brick walls in receiving loads (axial and axial-lateral). Abaqus (Simulia 6.10.1) Explicit is used as validation in predicting the form of failure that occurs in the composition of the brick Wall which receives load.

Abstract

One of the bridge projects in Kalimantan is built on soft soil. Soft soil has poor bearing capacity, low shear strength and permeability, and high compressibility. One of the substructures of the bridge project, consisting of two spun pile points, experienced failure (exceeding the allowable inclination, indications of breakage at a depth of -8,000 mm, and failure to achieve the planned bearing capacity). The failure occurred after excavation for the pile cap was carried out.The additional load from preloading embankments and a spun pile stockyard, located 20,000 mm and 15,000 mm away, caused lateral deformation in the existing soil. This lateral deformation influenced additional deformation and bending moments in the failed spun piles. An evaluation of the additional load on the spun piles was conducted using the Finite Element Method with Plaxis 2D software. The additional load from the preloading embankments and stockyard was analyzed to determine its impact on the spun piles.The analysis showed that the additional load from the preloading embankments and stockyard caused lateral deformation, leading to deformation and bending moments in the spun piles. However, this additional load alone was not sufficient to cause failure in the spun piles.
