To analyze concrete and steel structure (SAP 2000 ver.14) that combined with MS Excel in order to facilitate reporting.Basic Calculation PrinciplesFoundationa.Determination of working load based on structure analysis results.b.Analysis of soil bearing capacity based on soil test results. Soil test data for design requirements according to Terzaghi or Meyerhoff method is the weight of soil volume, friction angle, and cohesion. The analysis result can determine whether the foundation needed or not.c.Based on result of soil investigation, have a bearing capacity and pile size recommendation at certain of depth. The method used to determine bearing and friction capacity divided into 2; pile bearing capacity in granular and cohesive soil. Pile bearing capacity in granular soil are calculated by Meyerhof Method.The smallest bearing capacity is choose from some of the above methods.d.Determination of soil test deterioration correlated with allowable decrease. The methods used are as follows:-Poulos and Davis Methode.Pile Safety factor that suggested by Resse and O'Neill (1989):-Monumental Building, between 2.3 - 4-Permanent Building, between 2 - 3.4-Temporary Building, between 1.4 - 2.8The smallest value is for the good control factor and the higher value is for the worst control factor.Structurea.Equivalent static method is used for regular symmetrical building shape.b.Determine the working load.c.The working load is included dead load (DL), live load (LL), earthquake load (quake consists of Eqx and Eqy), and wind load (W). Eqx earthquake load is the earthquake loads that have same direction with the X coordinate, while the Eqy has same direction with Y.d.Earthquake load of coefficient = 0.09 (C).e.Analyze using various combinations of the above loads. The program will provide the calculation results of the higher influence load. Load combinations that used are as follows:-COMB 1 = 1.6 x DL-COMB 2 = 1.2 x DL + 1.4 x LL-COMB 3 = 1.2 x DL + 1.0 x LL + 1.6 x W-COMB 4 = 1.2 x DL + 1.0 x LL + 1.0 x Eqy-COMB 5 = 1.2 x DL + 1.0 x LL + 1.0 x Eqxf.Formula of bridge deflection for truss construction control as below: = L / 360, where: = deflectionL = length of bridge.g.The output will come out from the biggest effect above, whether the dimension of added capacity is worth or not. If the dimension is not worth, then dimension replacement to the bigger value is needed. There is auto select feature at SAP program, where the program will choose the most economical dimension from the input dimension of data entered. The recordings of each load combination can be displayed as consideration for further analysis.h.Output analysis that will be used are as follows:-Joint Reaction (placement reaction). This output is used for foundation calculation.-Rod Style, consist of moment, latitude force, and axial force. The output of is used to determine bolt capacity on design steel frame bridge.-Joint Displacement. The output is used to determine whether the deflection is eligible or not.-Reinforcement. The output is in the form of longitudinal reinforcement stirrup area at reinforced concrete construction.Soil SupportSoil bearing capacity analysis generally is divided into 2 (two); clay and sand soil bearing capacity. Terzaghi analysis method commonly use in the analysis of soil bearing capacity. The data required is the weight of soil volume, friction angle, cohesion, foundation dimensions, and working load. Based on data obtained from fromTerzaghi table by input friction angle, these values can be obtained (Nc, Nq, and N). The results of above analysis is ultimate bearing capacity (qu) that still have to be divided by safety factor. The amount of safety factor is ranged between 2.5-3. Carrying Permit (a) will be obtain after split it with safety factor. This value is use to determine the soil/land bearing capacity.Result of Structure DesignPipelineThe chosen pipeline material based on analysis is GRP pipe. The GRP pipeline are higher the pressure that the pipe is required to hold, the greater the strength requirement and thus the greater the wall thickness necessary to withstand that pressure.The maximum pipeline pressure of Water Conveyance and Integrated Dam Operating System for Bandung Area is PN.16 (1.6 MPa). So the pipeline to be used is GRP pipe with pressure number (PN) 16. Pipeline thickness for each pipe diameter that will be used can be seen at table below.Nominal DimensionOutside Diameter (mm)Thickness (mm)Weight (kg/m)
