Abstract

This paper investigates shear behaviour of reinforced concrete using multi-surface plasticity model. This analysis uses nonlinear finite element simulation using 3D-NLFEA finite element package. The experimental data adopted from the results of experimental test on eighteen beams where nine beams carried out by Bresler and Scordelis in 1963 and similar nine beams carried out by Vecchio and Shim in 2004. The constitutive model for the concrete material which used in this simulation is based on the plasticity-fracture model and considered the tension stiffening effect for the concrete. The result of the numerical simulation latter compared with the experimental test including load-deflection response, cracking pattern, and failure mode. Based on the analysis result, it was found that the load-deflection response shows slightly higher response compared with the experimental result. However, the cracking pattern and failure mode of the beam shows good result which is in compliance with the experimental test.

Abstract

Awareness about driving safety is still lacking among motorcycle users. As the provincial capital of East Nusa Tenggara (NTT), Kupang city accounts for the largest number of accidents in NTT with 70% of the total accidents involving motorcycles. It is important to measure the extent to which riding characteristics affects and causes road accidents since humans as the riders are the main factor in traffic accidents. A questionnaire was distributed to the motorcyclists. The data collected from 212 respondents was analysed with the multivariate logistic regression method. The analysis result states that the motorcycle mileage and the motorbike ownership hold the most influence on the incidence of motorcycle road accidents, where the further the motorcycle riders travel, the higher the probability of them to get involved in a road accident. Meanwhile the more units of motorcycle owned, the lower the probability of them to get involved in a road accident.

Abstract

The development of geopolymer concrete is one of the most significant breakthroughs to replace the OPC concrete causing global warming issues. Investigations on the structural behavior of geopolymer concrete are limited and still need adjustments in numerical simulations to experimental results in previous studies. This study investigated the flexural behavior of geopolymer concrete as a structural member using the numerical method. The utilization of the finite element method is an alternative to widely determining the structural behavior of geopolymer concrete as a construction material. In this study, the author refers to the research conducted by Pham et al. The research developed a four-point bending test with variations in tensile steel reinforcement ratio. The results of the experimental tests that Pham has carried out will be verified by numerical simulation in three dimensions. The validation of experimental specimens with numerical specimens is done to compare the moment-curvature and the crack pattern of concrete. Numerical investigation accurately captures the structural behavior of moment-curvature and crack pattern of geopolymer concrete. The moment maximum deviation between experimental and numerical results is 1.3 to 2.4%. However, there are differences in the number and length of cracks in the bending moment area. The difference of crack pattern in the bending moment area between experimental results and numerical results due to the modeling did not consider the input of fracture energy. The experiment from referenced studies did not include fracture energy data, so the 3DNLFEA modeling used the fracture energy value of OPC concrete.

Abstract

Liquefaction is a phenomenon where the saturated sandy soil experiences highly excess pore water pressure and loss of effective stress between soil particles simultaneously due to an earthquake. It will have an impact on building damage or failure which laid on sandy soil. Study location was selected at the New International Airport in Kulonprogo, Yogyakarta which was built on loose sandy soil and coincidentally categorized as highly earthquake zone. Based on this, an experiment model was carried out to analyze the behavior of sandy soil when stabilized with Aspergillus fungus as the microorganisms. The loads derived from dynamic loads (earthquake loads) and it will also analyze the changes of soil parameters after the soil stabilization. In a previous study using a fungus with the type of Rhizopus oligosporus, it resulted in a significant increase in soil consistency under certain conditions of water content. From the experiment, it is known that the appropriate percentage of soil mixture consists of ordinary sand with a percentage of 62% plus silt and clay with a percentage of 38%. Aspergillus fungus isolates at a concentration of 10-2 showed good tissue growth and without the presence of foreign substances.

Abstract

Geopolymer concrete that has polymer formwork is very likely to be used as reinforced concrete material with several advantages. The advantages of geopolymer concrete when compared to portland cement concrete are: resistant to acidic environments (corrosion resistance), better bond strength of reinforcement with concrete material, stable at high temperatures, higher fracture energy. Previous experimental studies found that the tensile strength, bond strength, and fracture energy of geopolymer concrete were better, leading to the hypothesis that the ductility value of geopolymer concrete was better than portland cement concrete. The identification of ductility values based on the compressive strength of concrete will be carried out in research using the finite element method using the 3D ATENA program. Several specimens with compressive strength of 25 MPa, 30 MPa, 35 MPa, 40 MPa, and 45 MPa were compared with their ductility values. The results showed that the 25 MPa specimen had the highest ductility value with 5.33, while the lowest ductility value is 45 MPa specimen with 3.39.

Abstract

Abstract: This study presents the modeling of the pull-out behavior of deformed bars embedded inside the reinforced concrete element. The simulation uses an in-house finite element package called 3D-NLFEA. Sufficiently small solid elements that consider the frictional resistance and mechanical interlocking between the bar thread and the concrete matrix were used in the simulation. The effect of concrete compressive strength, cover thickness, and stirrup configuration on the pull-out capacity of the modeled specimens are investigated thoroughly. The modeling found out that the 3D-NLFEA package can capture the bond-fracture process at the interface between the bars and concrete. The fracture that occurs in the concrete was dominated by tensile splitting failure. The presence of stirrups that confined the concrete and restrained the crack propagation significantly influences the pull-out capacity, cracking pattern, and failure behavior at the bar interface with the concrete. The analysis results from 3D-NLFEA are also compared with the 3D-RBSM analysis results available in the literature. From the comparison between the two packages, it can be concluded that the analysis result from 3D-NLFEA is somewhat more conservative compared to the 3D-RBSM.

Abstract

The embankment dam has the advantage that it can be built in all sub-base conditions although poor topography, but the weakness is seepage, so research on seepage is needed. This study uses numerical modelling with the GeoStudio program: SEEP/W and SLOPE/W. The data used is data from the Tugu Dam, Trenggalek, while the subbase data used five soil types, namely clay, silty clay, silt, silty sand, and sand. This research simulation is divided into two; the first simulation is the condition of the soil characteristics remains with the water level increasing every 5 meters from the base elevation of the dam to below the floodwater level;. In contrast, the second simulation is the condition of the water level elevation remains constant, but the soil characteristics change. Each simulation will be checked for seepage discharge and soil stability. The first simulation results show that seepage discharge and water level elevation have a logarithmic correlation with R2 > 0.75. The largest seepage discharge of 1,90 x 10-3 m3/s is sand soil, while the smallest is clay soil of 1,47 x 10-9 m3/s. The results of the second simulation show that the seepage discharge and saturated volumetric water content also have a logarithmic correlation, but some results cannot be used because they have an R2 value < 0.75. From the two simulations, the seepage discharge that occurs is said to be safe because it is below the average annual runoff which is 1% of the 10-year re-flood discharge calculated using the Nakayasu Synthetic Unit Hydrograph (HSS) which is 5.99 m3/s, and the safety factor of slope stability is > 1.2 then the dam is considered stable.

Abstract

The majority of traffic accidents in Surabaya are dominated by motorcycles and drivers which whom mostly were teenagers This study aims to examine the relationship between attitudes, driving behavior, and traffic accidents among young motorcyclist in Surabaya. The study used a primary dataset of 435 motorcyclists from 17to 25-year-old. This study uses a structural equation modelling approach to determine the relationship between attitudes towards risky driving behavior, driving behavior, and traffic accidents. The driving behavior parameters used are divided into six parameters: traffic errors, speed violations, control errors, traffic violations, safety violations, and stunts. The results of this study indicate that all driving behavior parameters are significantly influenced by the driver's attitude towards risky driving behavior. In which the parameters that have a significant effect on traffic accidents are traffic errors and traffic violations.
