Structural Engineering: Seeing the Big Picture
نویسنده
چکیده
The state-of-the-art of progress of structural engineering over the last 50 years is examined in three areas: (1) The spatial idealization of structural elements in the form of kinematical assumptions; (2) The constitutive idealization of materials in the form of generalized stresses and generalized strains relations; and (3) The computational implications of solution strategy in the form of closed form, approximate, and numerical procedures on the structural level.

STRUCTURAL OPTIMIZATION USING BIG BANG-BIG CRUNCH ALGORITHM: A REVIEW
The big bang-big crunch (BB-BC) algorithm is a popular metaheuristic optimization technique proposed based on one of the theories for the evolution of the universe. The algorithm utilizes a two-phase search mechanism: big-bang phase and big-crunch phase. In the big-bang phase the concept of energy dissipation is considered to produce disorder and randomness in the candidate population while in ...
متن کاملFeature Selection in Structural Health Monitoring Big Data Using a Meta-Heuristic Optimization Algorithm
This paper focuses on the processing of structural health monitoring (SHM) big data. Extracted features of a structure are reduced using an optimization algorithm to find a minimal subset of salient features by removing noisy, irrelevant and redundant data. The PSO-Harmony algorithm is introduced for feature selection to enhance the capability of the proposed method for processing the measure...
متن کاملIMPROVED BIG BANG-BIG CRUNCH ALGORITHM FOR OPTIMAL DIMENSIONAL DESIGN OF STRUCTURAL WALLS SYSTEM
Among the different lateral force resisting systems, shear walls are of appropriate stiffness and hence are extensively employed in the design of high-rise structures. The architectural concerns regarding the safety of these structures have further widened the application of coupled shear walls. The present study investigated the optimal dimensional design of coupled shear walls based on the im...

متن کاملSeeing versus Arguing The Moderating Role of Collaborative Visualization in Team Knowledge Integration
This paper sheds light on the communicative process through which experts and decision makers integrate their domain specific knowledge in decision making situations and argues for the benefit of knowledge visualization. We present a second order model for knowledge integration that reflects the main communicative challenges of such interactions. These are: unequal participation, a lack of comm...
