Abstract

Many structural systems are available to build a bridge. One of them is prestressed concrete bridge. The purpose of this research is to review the design of prestressed concrete bridge using SAP 2000 ver. 14 software.This research use elastic method on prestressed concrete, and ultimate method on the design of the other structures on the bridge. Whereas finite element analysis (FEA) with SAP 2000 ver.14 is used on traffic load analysis . From the analysis results, the longitudinal girder requires bending reinforcement of 12 D13, skin reinforcement of 6 ∅13, and 18 strand with dia. of 0.5" in each tendon. There is a difference with existing design which use bending reinforcement under the minimum requirement, whereas the strand used, meets the recent code.Slab requires bending reinforcement of ∅16-200, shrinking reinforcement and temperature of ∅13-250, however the existing design used denser reinforcement, this difference is due to changes in the bending reduction factor which follows the recent code of 2013 .Diaphragms requires bending reinforcement of 2 D28, skin reinforcement of 5 ∅13, and shear reinforcement of ∅13-500. this difference is due to changes in the reduction as well. Whereas in the shear reinforcement used by the existing design has met the recent code.Barrier wall requires bending reinforcement of ∅19-150 for the thickening area below the wall, ∅13-150 for the above area, and shear reinforcement of 10 ∅13, thus the reinforcement used by the existing design has met the recent code. The conclusion that can be taken is that the reinforcement used for the main structure component is correct, but some bending reinforcement are used under the need of ρmin and concrete standard of 2013. Keyword : bridge, prestressed concrete, SAP 2000 ver. 14

Abstract

Paving block is a composition ingredient construction made from mixture of portland cement or a kind of adhesive hydrolysis, water, and aggregates with or without other ingredients. Concrete bricks can colored as original color or given substance color on composition and used for page both inside nor outside construction. In this study the process of manufacture of paving blocks will use a mix of soil and chalk. Moreover, soaking of the paving blocks that are expected to increase the strength of paving blocks is according to SNI 03-0691-1996. Soil samples tested were from Kota Baru, South Lampung. Composition blend of soil and chalk with variation time to soak is 7 days, 14 days, 21 days, and 28 days, as well as to the treatment of pre-combustion and post-combustion of the sample of paving blocks. Based on the results of physical testing the original soil, USCS classify soil samples as fine-grained soil and belong to the group ML. Results from this study is the manufacture of paving blocks using silt soil and chalk soil material that does not meet the specifications of SNI 03-0691-1996. This is because the weakness on modification compactor which are use when make a sampel. For the compressive strength of paving blocks pre-combustion and post-combustion are best shown in soaking time of 28 days. The compressive strength that generated as a whole still does not meet the specifications of the paving block SK SNI 03-0691-1996 that is a minimum compressive strength at 85 kg/cm2. But value of water absorption meets the specification 03-0691-1996 which is 3%-10%.Keyword : Paving block, slit soil, compressive strength, soil burning.

Abstract

Roads are the transport infrastructures which play an important role in supporting the economicgrowth of a region. Therefore it is necessary to do maintenance efforts so that the roads canfunction optimally.One of them is by adding overlay. The selection of methods become a factorthat must be considered before doing flexible pavement overlay design. It is because of improperplanning can cause damaged or uneconomical construction of roads. Along with the technologicaladvances, methods of overlay flexible pavement design based on deflection also undergone manymodifications such as“Pedoman Perencanaan Tebal Lapis Tambah Perkerasan Lentur Pd T-05-2005-B”and “Pedoman Interim Perkerasan Jalan Lentur No.002/P/BM/201”. The purpose of thisresearch was to determine the most optimal and most efficient life cyclecost of overlay design inthe roads performance improvement project of Batas Kota Metro-Gedung Dalam. From theanalysis results show that the design results by using Pd T 05-2005-B were thinner than PedomanInterim No.002/P/BM/2011. It was caused by several factors such as the analysis of traffic,temperature correction factor, and the types of materials used. The indicator value of theinternational roughness index (IRI) is predicated by emperical equations and the design life of 20years, obtained the lowest lifecycle costs are the result of design methods Pd T-05-2005-B. Theresults of the analysis also showed that the cost at the end of the design life methods Pd T-05-2005-B less than Pedoman Interim No.002 /P/BM / 2011.Keywords :Road, Overlay, Life Cycle Cost
