BEHAVIOR GROUPS OF PILE TO VARIATION OF AXIAL OR LATERAL LOAD USE SOFTWARE PLAXIS 2D ON SOFT SOIL Musta’in Arif
Journal of Civil Engineering Vol 31, No 2 (2011)
Publisher : Institut Teknologi Sepuluh Nopember

Refer to Journal “ Numerical Analyses of Load Tests on Bored Piles, 2004” From the research results we can obtained that the conclusion from the Mohr Coulomb material model is more rigid than hardening material model , and the Soft Soil material model is more rigid than Mohr Coulomb material model. It is because there are difference from the formula that used in each methods.This final task goal is to compare some of configuration form of the pile group, in which consist of 2, 3, 4, 6, and 8 piles at one configuration with the distance between 2Ø and 4Ø to keep the axial or lateral load using software Plaxis 2D with material model: Mohr Coulomb, Hardening and Soft Soil. Based on calculation results using Plaxis 2D obtained result that the distance’s changes between piles will cause the addition from the ability of piles to keep axial and lateral load for same load. Then the distance’s changes between piles can reduce the decrease and deflection from piles. This study of the three material models, namely MohrCoulomb. Hardening, Soft Soil has the results of the analysis with the difference ranging from 0-1%.

LESSONS LEARNED FROM THE 2010 CANTERBURY EARTHQUAKE AND AFTERSHOCKS, NEW ZEALAND Sugeng Wijanto; C.W.K. Hyland

A moderate M7.1 earthquake hit Canterbury on Saturday, 4 September, 2010 at 04:35:46 a.m. New Zealand time (GMT +12). It was expected to be the most damaging ground shake since the 1931 magnitude 7.8 Hawke's Bay earthquake. The epicentre was located approximately 45 km west of Christchurch, in a rural area at a depth of 10 km. There were followed by more than thousand aftershocks had been measured. An aftershock M6.3 was recorded at 12:51 pm on Tuesday, 22 February 2011. The epicentre of the aftershock was approximately 10 km south-east of the Christchurch Central Business District (CBD), near Lyttelton, at a similar depth to the initial earthquake and caused much more severe damage to CBD and residential areas nearby. Lessons learned from the Canterbury earthquake and its aftershocks are a timely reminder to Indonesian structural engineers of a number of things with respect to seismic design, construction practices and post disaster evaluation. These include: The importance of implementing the latest seismic loadings and design technology into new and existing structures without undue delay; The need to maintain effective Building Code enforcement and post-earthquake audit process, including the keeping of publicly transparent compliance records; The important role of the design engineer in observing and auditing the interpretation and implementation of the design; Vigilance to prevent improper substitution of materials and ill-considered design changes; The importance of ongoing continuing professional development and education for design, construction and building code enforcement officials. This paper also discusses the need of having a guide for conducting post-earthquake structural repairs as including a quick way to identify appropriate repair strategies.

GEOPOLYMER CONCRETE USING FLY ASH, TRASS, SIDOARJO MUD BASED MATERIAL Januarti Jaya Ekaputri; Triwulan Triwulan

This paper presents the results of investigation to assess the mechanical properties of geopolymer concrete made with fly ash as a base material. Previous study showed that the compressive strength of geopolymer concrete were dependent on pozzolanic materials used and the concentration of activator solution in the mixture. The effort to use Sidoarjo Mud and trass as an additive material in the mixture was investigated in this study to analyze the mechanical properties of the concrete. NaOH solution mixed with Na2SiO3 was used as the activator solution which varied from 8 M to 14 M. Ratio of Na2SiO3 to NaOH solution by mass were also varied from 0.5 to 2.5 Trass and Sidoarjo Mud were introduced as the filler and mixed with fly ash to replace the volume of fly ash. Compressive strength test of cylindrical specimens at 28 days, split strength test and porosity test were carried out comprehensively to compare the specimens from each composition. The results showed that the best concrete will be produced when denser NaOH solution was used. Ratio of Na2SiO3 to NaOH in the solution also plays an important role to improve the mechanical properties of concrete. The result of this study also shows that Sidoarjo Mud is a prospective material for making geopolymer concrete.

Quality control problems of great importance in supporting the successful development of the project, due to carry out quality control results will be obtained in accordance with the terms specified techniques. Form of the test object in the implementation of quality control may affect the accuracy of the results, especially on standardized test specimens are not generated from the test piece drill cores. There are several sizes of test objects used in accordance with regulations such as PBI 1971dan British Standard (BS) using the test specimen size 15x15x15 cm 3, 20x20x20 cm3. ACI 318, ASTM C42/C42M 2003, using a cylindrical test specimen dimensions 15x30 cm. There is a discourse of the specimen size 10x20 cm due to the size of the specimen is sufficient in number when using a laboratory mixer other than that estimated difference with the test results are not significant 15x30. Test specimen 15x15x15 and 20x20x20 cm cube estimated results are less rigorous than the cylinder, because the cube distribution voltage is not equal than the cylinders which form a circle so that distribution is the same if the specimen is pressed. Taking the test object with a core drill is sometimes produced beyond the standard test specimen is less than 15 cm, 10 cm even for the special conditions of the drill core of 5 cm. Reasons mentioned above the authors conducted research on "Influence of aggregate diameter on compressive strength and the influence of variation of L / D of the compressive strength and the results will be compared with ASTM C42 / C42M-2003. In this study made two kinds of mixed concrete fc' = 225 kg/cm2 and fc' = 400 kg/cm2, because concrete is the most widely used in practical and concrete categories included normal quality concrete. Stage is the initial stage of examining the influence of the maximum aggregate diameter on compressive strength, to find the optimum diameter for compressive strength.

“Fiber reinforced concrete” is made from cement, fine aggregate, coarse aggregate, water and many fibers that randomly spread within the mixture. To increase the ability of concrete to resist tensile and flexure, efforts are done by giving reinforcements or other material such as fibers in the tensile region.In this research the examination done in experiment with add plastic fibers of plastic benneser (poly-acrylonitryl styrene) in concrete mixture, with the percentage between 0% - 1, 00%.Otherwise in this research, the use of high concrete quality, are developing from the past research would have done in Unitomo. And the purpose of this research is to know the behavior of the mechanic phenomena like stretch and ductility from fibers concrete of beneser of higher concrete quality as united. So with this could be compare with the higher concrete quality without fibers. The concrete sample of fibers composite is made with three different things like: cylinders sample with size Ø10 and 15 cm high 20 and 30 cm, and block sample with size 15 X 20 X 60 cm. Cross section of full fibers composite and partial is used by block sample, only in stretch area below the neutral lines. The result says that: strengthened in splitting in a cylinder sample between 12, 56 – 27, 07 %, and the power of ductility from the block sample of full fibers between 12, 95 % – 20, 19 %, and the partial is 12 – 16, 57 %.
