Abstract
Structural reliability analysis is increasingly used in conjunction with the design of offshore structures which have high uncertainty. Two problems i.e. reliability and complexity of the structures resulted in Monte Carlo Finite Element Method (MCFEM) method of analysis. In the first part of this research, we will show results comparison between deterministic analysis software made in Proposed Software and analysis using commercial established software. In this case, object will assume as a simple Plane Truss structure with multi degrees of freedom applied dynamic load in the support of structure. The second part after obtaining a deterministic result compared by commercial software, further we will apply MCFEM algorithm to the deterministic analysis algorithm which has been made. The results of this research, contains a new procedure in the form of reliability simulation algorithm by combining Monte Carlo Simulation and Finite Element Method in Dynamic Model.
Highlights
Structural design should involve a various random variables both demand side such as environmental load, live load, etc. and supply side such as material strength, dimension, etc
Based on the results of literature study and review related to dynamic model structure analysis which will be applied Monte Carlo method, it is necessary some stage in determining the movement in the dynamic model structure of a simulation, such as determining the structure configuration based on the desired element type, perform the modal analysis and determine the method which is used in completing the dynamic model motion equation
After random variable is input, it must be repeated as much as the predetermined iteration by calling to 3 random parameters previously. These 3 parameters are transformed to new variables E, Madd, and uc which are used as inputs in calculations of simple Plane Truss Structures
Summary
Structural design should involve a various random variables both demand side such as environmental load, live load, etc. and supply side such as material strength, dimension, etc. Structural strength and load will be simplified as the "maximum" (load) and the "minimum" (strength) which are largely based on deterministic data. This approach is not relevant since random behaviour of some structures are increase. Some researchers have attempted to derive equations to predict these random variables in term of stochastic approach [2] This approach will be a new reference to structural design procedure. The complexity of structural geometry is not possible to be analyzed by using manual calculations Another helpful way to solve it, is by using computer-aided calculations which is known as numerical simulation [3]. At time went on Matlab came to dominate the market [7]
