Performance-based optimum seismic design of reinforced concrete structures
TL;DR: In this article, a fully automated design methodology based on nonlinear response history analysis is proposed for the optimum seismic design of reinforced concrete (RC) structures, where the conventional trial-and-error process is replaced by a structural optimization algorithm that serves as a search engine capable of locating the most efficient design in terms of cost and performance.

Optimal design of structures subjected to time history loading by swarm intelligence and an advanced metamodel
Saeed Gholizadeh,Eysa Salajegheh +1 more
TL;DR: A new metamodeling framework that reduces the computational burden of the structural optimization against the time history loading is proposed and the most influential natural periods on the dynamic behavior of structures are treated as the inputs of the neural networks.

Life cycle sustainability assessment of RC buildings in seismic regions
TL;DR: In this paper, a life-cycle sustainability assessment (LCSA) framework was developed and used for sustainability quantification of reinforced concrete (RC) buildings subjected to earthquakes, and the sustainability through various stages of the lifetime of an RC building was obtained in terms of cost and downtime, environmental emissions and waste generation, and deaths.

Optimum design of steel structures with web openings
TL;DR: In this article, the optimal design of 3D steel structures having perforated I-section beams is formulated as a combined sizing, shape and topology optimization problem, and two distinctive formulations of the optimization problem are considered depending on the finite element discretization implemented for simulating the structural elements.

Earthquakes, Records, and Nonlinear Responses
TL;DR: In this article, the estimation of MDOF nonlinear structural response given an earthquake of magnitude M at distance R is studied with respect to issues such as the benefits and harms of first scaling the records, selecting records from the “wrong” magnitude, and alternative choices for how to scale the records.

Development and verification of a displacement-based adaptive pushover procedure
S. Antoniou,Rui Pinho +1 more
TL;DR: In this article, a displacement-based adaptive pushover procedure is presented, whereby a set of laterally applied displacements, rather than forces, is monotonically applied to the structure, and the integrity of the analysis algorithm is veried through an extensive comparative study involving static and dynamic nonlinear analysis of 12 reinforced concrete buildings subjected to four diverse acceleration records.
