Abstract

In a building construction project must have been a cost since high. Therefore, it is necessary to re-analyze with dianksan value technique. Value Engineering is used for alternatives or ideas which are for better cost results or lower than the price that has become a limitation with good limitations and quality of work. Value Engineering analysis in this study uses four job plans, among others: information stage, creative stage, analysis stage, and recommendation stage. In the creative stage of this research using alternatives - the best alternatives by replacing concrete repair and formwork. For the application of Value Engineering is applied to the work of Beam Work, Floor Plate Work and Column Work. From this stage, the best alternative used in the construction of RSUD Sanjiwani Gianyar Service Building is alternative IV by using wiremesh correction and 8x use formwork. Thus, resulting in cost savings of IDR. 4,432,339,572.59 or 20.77% from IDR. 21,337,615,447.66. Efficiency of execution time on the work of the structure 31 days. This research can be concluded that the application of Value Engineering in the Construction of RSUD Sanjiwani Gianyar Service Building can reduce the cost of the planned reinforced concrete structure work.

Abstract

This paper presents a shear buckling analysis of corrugated web I-girder beam using nonlinear finite element analysis. An in-house finite element package called 3D-NLFEA is used in the simulation. The steel material is modelled as solid elements with one-eight aspect ratio between the element size and its thickness. The double sine waves equation is used to generate the initial imperfection in the corrugated web. The nonlinear geometry deformation, which is essential in capturing the buckling behavior, is considered using the 2nd order analysis in 3D-NLFEA. A comparison with the carried out experimental test in the laboratory showed that the peak prediction from the analytical model was in good agreement. Furthermore, using the double sine waves equation as the initial imperfection can closely predict the buckling mode and shapes of the corrugated web I-girder as obtained from the experimental test.
