Abstract

Reinforced concrete (RC) beam is one of the structural elements that is often encountered in field applications and is a considerable element of its role in carrying flexural load. The purpose of this research is to analyze the pure bending behavior of RC beam in the form of stress on the reinforcement bars by using finite element method. Finite element analysis is done by using software LUSAS v.16. The load was applied at 2 points at a distance of 1/3 of beam span  from each supports and it was gradually increased until the beam  cracked. The result of yield tensile strength of reinforcement bar was 358.65 MPa. It was found that the tensile stress of the tension reinforcement bars in the event of  first crack was 72.1 MPa, while the tensile stress of these bars in the event of maximum applied load was 379.75 MPa. It can be concluded that the tensile reinforcement bars at the maximum load gained from the finite element analysis has yeilded. Keywords : Reinforced concrete beam, finite element, LUSAS v.16, tensile stress, first crack, maximum load.

Abstract

At the time of installation the distance between the shear reinforcement is not planned properly. This affects the serviceability of reinforced concrete blocks. This study aims to see the effect of the planned shear reinforcement which is not according to the initial plan. So, an analysis of the effect of shear reinforcement on deflection was carried out using the LUSAS Finite Element. The results of the LUSAS Finite Element analysis show that the BS2 beam model with a maximum load of 40.5 kN has decreased deflection by 33.53 % against the planning according to SNI 03-2847-2019 (BS1) which has a maximum load of 46.55 kN. Furthermore, for the BS3 model with a maximum load of 38.69 kN, the deflection decreased by 35,03 % from the planning according to SNI 03-2847-2019 (BS1) which had a maximum load of 46.55 kN. It can be concluded that the spacing of the shear reinforcement can affect the deflection of the beam. Keywords : Beam, Shear Reinforcement, Deflection, LUSAS

Abstract

Indonesia is part of an area that is known for earthquake and volcano eruption activities. Because of this, one of the structural planning concept in Indonesia is by analyzing structure performance after earthquake activity. The purpose of this research is to identify performance and distribution of plastic hinge on structure storeyed buildings at Indonesia area with high intensity earthquake by using nonlinear static analysis method. Structure model is varied by height and number of floors, Model 1 is building with 5 floor, Model 2 is building with 10 floors, and Model 3 is building with 15 floors.Building is made from reinforced concrete with constant height of 4 meters. Building model receives earthquake load in the form of response spectrum of earthquake area with high ground accelaration (g). Earthquake area that is picked is at Banda Aceh with two soil condition (moderate soil and softsoil). Structure performance is decided by using ATC-40 code which is affected by target displacement. Method which is used to obtain target displacement is ATC-40 capacity spectrummethod and displacement coefficient FEMA 356. Analysis result shows performance level of all three models IO (Immediate Occupancy) are similar in moderate soil and soft soil condition.Keywords: moderate soil and soft soil condition, nonlinear static analysis, plastic hinge, response spectrum, structure performance, structure storeyed building.

Abstract

A flat slab is a building structure component that uses a portal system and a plate that is directly supported by a column with or without plate thickness at the top of the column (drop panel). Flat slabs are still rarely used in the city of Pekanbaru, because there are still many conventional plates used. To determine the performance of each structural system, it is necessary to examine the influence at the flat slab and conventional plate system to the performance of the structure of the building. The purpose of this research is to identify the effect of flat slabs on the reinforced concrete open frame structure systems and comparing them with conventional structural systems. Two models were constructed, model 1 was the original Transmart Pekanbaru Building model, while model 2 replaced the flat slab on the ground floor with a 600x400 beam. The results showed that the story drift value in model 1 was very large compared to a model 2 with a comparison value of 60,00 in the direction X and 11,50 in the direction Y. Based on story drift in model 1 and model 2, the building structure has met the requirements for the story drift permit of 0.6 on the ground floor and 0.1 on the 1st to 3rd floors. So that it can be concluded that conventional systems are better than flat slabs because beam factors greatly affect the displacement of a building structure.Keywords: flat slab, conventional plate, story drift

Abstract

One of the simplification model of structure in the structural dynamic engineering was converting the model of a structure into the system that has mass, stiffness, damping percentageand number of Degree of Freedom (DOF) whether in single number (Single Degree of Freedom) or multi number (Multi Degree of Freedom) as its components. Yet the application of model SDOF system was used as fundamental analysis and had to be developed for MDOF system. The research of MDOF system had become necessity to be continuously done in order to improve the previous existing analysis method. One of the method that potentially can be used was with Artificial Neural Network (ANN). Thus why this research was aimed to identify the capability of ANN in predicting the system responses. The analysis of system with 4, 6 and 8 DOFs that was subjected to dynamic excitation such as sinusoidal, triangular, rectangular and ramp load was done with Newmark-β method listing program of FORTRAN. Then analysis continued with Backpropagation Neural Network (BP-NN) using MATLAB program. The input data for BP-NN were heights (H), mass, stiffness, damping value, natural period (Tn) and dynamic load factor (DLF) with system responses as target data. The result had shown that variation of dynamic loads and system parameter had affected the value of system responses. While BP-NN training result showed its ability in predicting the system responses was decreasing from displacement to velocity and acceleration. It could be seen within the degradation value of regression (R) from 0.99-0.84, the increase of Mean Squared Error (MSE) from 1.19×10-7-0.7654 and error percentage from 5%-41%. Therefore ANN method was not capable to be used in predicting the responses of MDOF system under dynamic loads.Keywords: MDOF system, dynamic load, Backpropagation Neural Network, Newmark-β, displacement, velocity, acceleration

Abstract

Indonesia one of the countries that prone to earthquakes which is tectonic and volcanic. Earthquake can damage a building, therefore the planning of earthquake resistant building is a requirement for an earthquake prone areas like in Indonesia and that planning must notice to the response of structure. One of the solution to predict the structural response and the damage level of multilevel steel portals is using the Artificial Neural Network (ANN). Thestructure model that author review is a multilevel steel portals which consisting of 3 models (5 levels, 10 levels and 15 levels). The structure is modeling with the finite element softwareand receives earthquake loads based on the time history of the Cape Mendocino earthquake that will be scaled on 10 capital of the provinces in Sumatera island. Artificial Neural Network(ANN) with backpropagation method is designed by using MATLAB program which is the input of this ANN is displacement, velocity and acceleration of three models that have beendesigned. The output that will be generated is damage level of the steel portal in the category of Safe, Immidiate Occupancy (IO), Life Safety (LS) or in conditions of Collapse Prevention(CP). Artificial neural network is trained by 8 earthquake data that owned by the capital of the provinces, and 2 remaining data from Padang City and Pekanbaru City that use forsimulation process. Based on the research, the model of artificial neural network has the potential accuracy to predict the damage level of structural between 90% -99%. From the result of simulation by ANN with 702 data from capital provinces of Padang and Pekanbaru City, 98,5% data could be predicted correctly by ANN. These results have shown that ANN is able to predict the damage level of multilevel steel portals in all of capital provinces in Sumatera Island.Keywords: multilevel steel portals, 3 structural model, structure response, time history, damage level, Artificial Neural Network.

Abstract

Concrete is the common material that is used on construction. Concrete will be subjected to loading during the construction until its service time. Continuous loading on concrete caused cracks in concrete. Cracks can also occur due to be changes in temperature, shrinkage, and also when the concrete was ready to casted that caused by cement hydration . The purpose of this study was to obtained crack patterns existed on reinforced concrete beam during the application of flexural load. The specimen used on this study was reinforced concrete beam with the cross section of 10 cm x 20 cm and with the length of 125 cm.

Abstract

One of the steel sections that is widely used is the C channel section. C channel sections are generally used as purlins. C channel beam has a large ratio of width to height. This can lead the element of structure to failure such as buckling. So, the stiffener was used on the beam to prevent buckling. This study aims to analyze the effect of using stiffener on the C channel steel section. The analysis of the effect of stiffener on flexural strength was carried out using LUSAS V18 finite element. The test object was modeled with 2 objects using stiffener and 2 objects without stiffener. The result of the numerical analysis using the LUSAS V18 finite element showed that the load capacity of B1-2 had increased by 5.88% from the B1-1. The beam in the strong axis direction without stiffeners had the maximum load of 17 kN with a deflection of 18.67 mm, while the beams with stiffeners had the maximum load of 18 kN with a deflection of 13.346 mm. In the weak axis direction, the result shows that the load capacity of B2-2 had increased by 20% from the beam B2-1. The beam B2-1 had the maximum load of 10 kN with a deflection of 18.29 mm, while the beams with stiffener had the maximum load of 12 kN with a deflection of 27.46 mm. So it can be concluded that the use of stiffeners can increase the load capacity.Keyword: C Channel Section, Stiffener, Deflection, LUSAS, Strong Axis

Abstract

Fire hazard can bring serious problems to reinforced concrete buildings. At combustion temperatures, heat from the fire propagates from the surface into the core of the concrete. This study aims to model the heat transfer on concrete and the results were compared to numerical method proposed by Wickstrom (1987). The specimen used in this study was a concrete cylinder with the diameter of 150 mm and the height of 300 mm. The specimen was exposed to a combustion temperature of 800oC with the combustion duration of 3 hours. The model carried out in the LUSAS v.16 program. Measurements were made at the distance of 19, 38, 56, and 75 mm from the perimeter of cylinder. The results of the study showed the difference in temperature increase using 2D, 3D, and Wickstrom model. For comparison between Wickstrom and 2D at a depth of 19 mm is 15.96%, for 38 mm is 43.57%, for 56 mm is 66.95%, and for a distance is 75 mm of 89.93%. Moreover, the results gained from 2D finite element analysis was 2,05% higher than 3D finite element analysis. The greater the depth of the review, the results between model and Wickstrom method will be much different. The average value of these results can be used as a reference value of the temperature increase at the point of review at a certain distance from perimeter of cylindrical concrete model under high temperatures.Key words: heat transfer, thermal conductivity, specific heat , LUSAS v.16, Wickstrommethod.
