Design optimization of welded steel plate girders configured as a hybrid structure

Negrín-Díaz, Iván Antonio; Kripka, Moacir; Yepes, V. (Elsevier, 2023-12)

[EN] This paper implements structural design optimization to improve the economic indexes of welded steel plate girders. The optimization problem is formulated in a way that allows the use of hybrid configurations, i.e., ...
Hybrid steel girders: Review, advantages and new horizons in research and applications

Terreros-Bedoya, Agusztine; Negrín-Díaz, Iván Antonio; Paya-Zaforteza, Ignacio; Yepes, V. (Elsevier, 2023-08)

[EN] Although it is still common practice to use homogeneous steel girders (same yield strength in the flanges and web), implementing hybrid configurations seems to be an excellent alternative to improve the performance ...
Metamodel-assisted design optimization in the field of structural engineering: A literature review

Negrín-Díaz, Iván Antonio; Kripka, Moacir; Yepes, V. (Elsevier, 2023-06)

[EN] Metamodel-assisted optimization is a valuable alternative to handle structural design optimization procedures, which are usually quite expensive and sometimes even prohibitive. This paper presents an up-to-date ...
Metamodel-assisted meta-heuristic design optimization of reinforced concrete frame structures considering soil-structure interaction

Negrín-Díaz, Iván Antonio; Kripka, Moacir; Yepes, V. (Elsevier, 2023-10-15)

[EN] It is well known that conventional heuristic optimization is the most common approach to deal with structural optimization problems. However, metamodel-assisted optimization has become a valuable strategy for decreasing ...
Multi-criteria optimization for sustainability-based design of reinforced concrete frame buildings

Negrín-Díaz, Iván Antonio; Kripka, Moacir; Yepes, V. (Elsevier, 2023-11-01)

[EN] This paper implements the multi-criteria design optimization of three-dimensional reinforced concrete frame building structures, considering aspects such as the realistic design of the elements, including foundations ...
