Research ArticleOpen accessHybrid Connection Simulation Using Dynamic Nodal Numbering AlgorithmAlongkorn Lamom, Thaksin Thepchatri, Wanchai RivepiboonProblem statement: The traditional dynamic nodal numbering algorithm was proposed for generating code number to support truss and frame simulation using only one element type, frame element; it facilitates the software development process. The traditional algorithm, however, supports simulation of only two types of connection: Hinged connection and rigid connection. In many cases, the problems consist of mix-connection and hybrid … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 8,199 accessesView PDF Cite

Research ArticleOpen accessHeuristic Algorithm in Optimal Discrete Structural DesignsAlongkorn Lamom, Thaksin Thepchatri, Wanchai RivepiboonThis study proposes a Heuristic Algorithm for Material Size Selection (HAMSS). It is developed to handle discrete structural optimization problems. The proposed algorithm (HAMSS), Simulated Annealing Algorithm (SA) and the conventional design algorithm obtained from a structural steel design software are studied with three selected examples. The HAMSS, in fact, is the adaptation from the traditional SA. Although the SA … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,345 accessesView PDF Cite
