Abstract

Large magnitude earthquakes often trigger liquefaction phenomenon in granular soil deposits. One of the major liquefaction events in Indonesia occurred during the 2018 Palu earthquake, which caused economic losses around 1.1 billion USD. Liquefaction can be mitigated by evaluating the risk and impact it will cause. The events can be modeled numerically by using the SPH method. SPH is a continuum method that doesn’t need to simulate numerical model. The advantage of using SPH is its ability to model large deformation phenomenon using Lagrangian approach. In this research, SPH was used to model the failure mechanism of 2D saturated granular soil column with 0.6 m x 2.0 m dimension. Soil constitutive model used is elasto-plastic, where plastic deformation is measured using Drucker-Prager failure criterion. The interaction between soil-water particles is represented by the seepage force, following the research model of Korzani et al. (2017). In this model, no external forces applied other than the gravity force. The simulation results are used to analyze granular soil deformation.

Abstract

The application of BIM in Indonesia in building planning which refers to SNI 1726:2019 is still very minimal. This research involves two different types of buildings, namely hotel buildings and hospitals. The modeling used is simple concrete building structure modeling with variations of 3, 9 and 12 floors in Revit as a model. The same BIM model is used in the Structural Analysis Robot and then the results of the two buildings are compared, namely the comparison of story shear and story displacement. The research methods used are data collection, BIM modeling using the latest software, and seismic analysis taking into account the parameters described in SNI 1726:2019. The results of BIM modeling and seismic analysis were then compared for both types of buildings.

Abstract

The Jlantah Dam is a multi-purpose dam that was built in 2019. Besides the benefits, the dam also has potential danger if it floods and cause overtopping. Flood discharge is influenced by rainfall and land cover conditions. BMKG noted that the La Nina phenomenon occurred in 2020 – 2022 which had an impact on increasing rain intensity. Apart from that, from 2017 – 2023 there has been a change in land cover in the Jlantah Dam catchmen area. This research aims to analyze flood discharge at Jlantah Dam with current rain conditions and land cover and evaluate the safety of the dam against overtopping through HEC-HMS flood routing. The results of the HEC-HMS flood discharge analysis show that there is an increase in average flood discharge of ± 3,27% from the 2017 study. Based on the results of the flood routing, the dam's freeboard at discharge return periods 2, 5, 10, 25, 50, 100, 1000 years, and PMF respectively: 4,2 m; 3,9m; 3,8m; 3,5m; 3,3m; 3m; 2,6m; and 0,9m. At the PMF discharge there was a decrease in the freeboard of 0,35 m from the 2017 study but it remained safe against overtopping. The flood reduction at return periods 2, 5, 10, 25, 50, 100, 1000 years, and PMF respectively: 33%; 33%; 32%; 30%; 29%; 26%; 24%; and 17%.

Abstract

The inelastic behavior of earthquake-resistant buildings is expected to be able to withstand the cyclic loads that occur due to earthquake loads. The inelastic behavior of a building can be seen from the force-displacement curve. The curve can be obtained using several approaches, but each approach can provide different values. In this study, a backbone curve will be constructed using three approaches, namely the analytical approach, XTRACT software, and the ASCE 41-17 method. The specimen under review is a rectangular column with a single cantilever test configuration. The review parameters were the type, spacing, and area of reinforcement as well as the axial force ratio. The backbone curve obtained is compared with the experimental backbone curve. Based on the analysis, it was found that the most conservative method was ASCE 41-17. Evaluation was conducted on the three approaches used and the parameters reviewed

Abstract

Volume instability in expansive soils due to changes in moisture content results in damage to the supporting structure. Soil improvement is one of the efforts made for soil improvement. Soil stabilization is one part of soil improvement. Appropriate soil improvement needs to be carried out to see the performance of the soil to meet post-construction stability requirements. Chemical stabilization using cementitious soil materials can improve the engineering properties of expansive soils. The research objective is to analyze the value of engineering properties of expansive soil with cement. Experimental research method to determine the value of California Bearing Ratio (CBR and Atterberg limits. Expansive soil was stabilized with cement with variations of 10, 12, and 14% cement by weight. As a result, the value of engineering properties increased, namely the maximum CBR value of 7.40% in the 14% variation at a curing time of 7 days. The smallest PI value in the 14% cement variation is 13.65%, there is a decrease in PI value with the addition of cement. In conclusion, engineering properties of soil with cement stabilization increase the CBR value of soil and decrease the Plasticity Index value.

Abstract

Clay soil tends to expand when wet and contract when dry, which can cause cracks in the soil or damage to the building structure above it if not handled properly. One effort that can be carried out is chemical stabilization using both conventional stabilization materials and the use of alternative stabilization materials, both organic and inorganic. The aim of this research is to increase the shear strength of the soil by adding varying percentages of 5%, 10%, 15% and 20% of concrete waste. The method used is an experimental method in the laboratory using SNI 3420:2016 testing for shear strength. The research results show that there is an increase in cohesion values ​​and shear angles along with the addition of concrete waste. The highest increase was found in the percentage of 20% addition of concrete waste to the original soil, namely the cohesion value was 0.400 kg/cm2 and the shear angle value was 24.567 0.

Abstract

The operation of a reservoir begins with a period of reservoir filling or impounding. In the process, reservoir filling will take a long time if the inflow discharge is too little, which can result in supply disruptions downstream of the dam. Meanwhile, if the inflow discharge is too large, it will fill the reservoir too quickly which can affect the completion of the remaining work and can increase the risk of dam collapse. The research aims to analyze the discharge into the reservoir and simulate and predict the duration and rate of water rise in filling the reservoir. The method used is the determination of watershed parameters with calibration and validation based on observation discharge data, followed by analysis of river flow discharge using FJ Mock. The Impounding simulation using the mainstay discharge of the FJ Mock model results in various inflow scenarios. The simulation results of the rate and duration of the most optimal reservoir water level rise to reach the Intake Gate elevation in the Wet Year is November at 0.79 m/day for 29 days. The normal Year is November at 0.68 m/day for 34 days. While in the Dry Year is December at 1.00 m/day for 23 days. Considering the safety factor, impounding should start in November because the water rise rate is quite large but does not exceed the regulations.

Abstract

Mentawai islands are one of the regions that utilize the tourism sector to support their development. Mentawai is a favorite destination for surfing tourists from abroad. In general, tourism in Mentawai island has a good impact on the local economy. Infrastructure development in the Mentawai island is still lagging behind compared to other cities in West Sumatera. The development process in Mentawai should receive serious attention considering that Mentawai is an prone area to earthquake and tsunami disasters. The increase in the potential for earthquake and tsunamis is not matched by the communit’s readiness to face them. To reduce the risk of loss live in earthquake prone area, earthquake resistant building standards are very important to implement. Earthquake resistant buildings must be applied from the planning stage, not just during the construction process. SDN 12 Muntei is one of the buildings that can be used by the public as an elementary school. Investigation of the initial design of the building foundation in previous research found that the allowable capacity of the foundation not be able to support axial load on the building, so a redesign of the foundation cross section was recommended. After redesigning the foundation with a fixed footing type as in previous research, it is recommended that the foundation be at a depth of (D) = 1.5 meter with a width of (B) = 1.3 meter. The Safety Factor (SF) value to determine the allowable capacity of the foundation (Qa) is taken as 3. From the results the analysis of the allowable capacity with new cross section dimension, the value of Qa= 378.76 KN and the value of the maximum load on building (Pmaks)= 339 KN. The results of this analysis show that the crosssection requirements and can be used.

Abstract

The existence of a swimming pool above the building plus the size of the swimming pool makes the designed structure must be safe for its users. One of the structural methods used is a combination of structures where the use of a steel frame beam structure is connected to a concrete column. The steel frame beam structure uses two H-beam steel profiles arranged in a Bailey frame model. The frame beam uses a HWF 350.350.12.19 arranged profile with stiffening using a 20 mm thick coupling plate. In this structure, all connections use the welding connection method. The use of a steel frame beam structure is expected to be able to support the load of a swimming pool that stretches 27 m x 20.5 m. To determine the behavior and response of the steel frame beam structure to the load, a stability analysis of the steel frame beam structure was carried out using an auxiliary program. From the results of the analysis of the compressive and tensile control of the axial force of the frame beam, it is able to support the swimming pool load with the largest compressive control value of bar B11 11994701.59 N > 8375985.50 N and the largest tensile control of bar B19 16317000 N > 10384957.50 N.

Abstract

The structural planning of the hospital is designed as an earthquake resistant building. The beam-column connection area is a vulnerable area that must be designed by taking into account the inelastic deformation in the event of an earthquake. Therefore, a floor slab diaphragm is used as an earthquake resisting system. In this study, the floor slab diaphragm is modelled as a rigid diaphragm and is expected to provide lateral resistance to a ductile structure. To determine the level of ductility of a structure, the pushover analysis method is used. Pushover analysis is an analysis to determine the level of collapse of a structure against an earthquake and can determine the level of ductility of a structure. From the analysis results, the ductility value for the x direction is 1.55 and for the y direction is 2.15. So, the behaviour of the building structure after being reinforced with a floor plate diaphragm has a partial ductility level with a structural performance level of Immediate Occupancy (IO), which means a condition where the structure is still safe and strong to use activities shortly after an earthquake occurs.
