Tujuan dari studi ini adalah untuk menganalisa dan mengevaluasi perencanaan pile cap di titik P10 pada proyek Fly Over Jamin Ginting dengan menggunakan metode strut and tie. Perhitungan metode strut and tie dilakukan berdasarkan peraturan ACI Building Code 318-2002, yang meliputi desain model strut and tie, besar gaya yang terjadi, serta penulangan pile cap.

Abstract — Brick wall is often used as partition separator on the inside as well as the outer cover of the building, especially for low and medium storey buildings in Indonesia. Due to architectural needs often on walls made openings such as windows, doors, etc. This study aims to find out how large the influence of openings area to the stiffness and strength of the structure.

Abstract — The Cibeet pipe bridge is a steel frame bridge that is used as an 8 inch pipe holder for distribution of crude oil. It is known that Bridge 2 has excessive deflection so it needs to be assessed and strengthened. The Bridge Assessment is intended to support the crude oil transportation infrastructure in accordance with applicable planning criteria and bridge reinforcement planning. By using an external prestressed reinforcement method, it is obtained with the aim of a steel frame bridge to reduce deflection on the bridge. The Cibeet 2 bridge also underwent construction with a ½ inch diameter cable with, fu = 270 ksi. The number of cables installed as many as 8 pieces.
