Abstract:   The theory of optimization has improved remarkably during the last four decades. The main part of optimizing investigations has been focused on enhancing buckling resistance which does not violate the economic feasibility of final design. The finite element analysis which is called ESO (Evolutionary Structural Optimization) is presented for optimum (or most ideal) design of c...

Based on the concept of "Robot Oriented Design" which was presented at the 5th international symposium on robotics in construction In June 1988, this paper proposes a design analysis for the "ROD" robot-oriented-design synthesis of structural elements. The structural elements are beam and column including their joining system. A systematic method for analysing the design of a structural joining...

This paper compares base shears computed from floor accelerations (inertial base shear) and column shears (structural base shear) for two mid-rise, multi­ story buildings due to a suite of 30 earthquake ground motions. The presented results demonstrate that the inertial base shear exceeds the structural base shear in the median by 10% to 20% and may exceed the structural base shear by as much a...

Fire engineering a building, in general, has one central performance objective – life safety – and property protection is rarely explicitly considered. The engineering is typically based on only one possible fire, which may not represent the most onerous scenario (or may be much too onerous to be considered realistic). Taking inspiration from fragility analyses used in seismic engineering, this...

We characterize the edge versus path incidence matrix of a series-parallel graph. One characterization is algorithmic while the second is structural. The structural characterization implies that the greedy algorithm solves the max 7ow problem in series-parallel graphs, as shown by Bein et al. (Discrete Appl. Math. 10 (1985) 117–124). The algorithmic characterization gives an e8cient way to iden...

In this work the distillation column sequencing problem is addressed through the Generalized Modular Framework, based on formal superstructure optimization techniques. The proposed method overcomes structural complexities through the use of systematically composed structural models incorporating all the feasible sequencing alternatives. The generated sequences are evaluated with respect to thei...

−An industrial scale hexane process is designed for the implementation of a fully thermally coupled distillation column (FTCDC). A semi-rigorous material balance and Peng-Robinson equilibrium relation are utilized in the structural design. The operational design is conducted with a commercial design program, the HYSYS. The design outcome of the structural design indicates it to be comparable wi...
