“…The corrugated steel plate has various favourable properties hence it is used in many structural applications. The most commonly used structural members in steel constructions were cold formed sections and hot rolled sections [2,3]. Now a days, cold formed sections are used in various applications compared to hot rolled members since the weight of hot rolled members are much heavier on comparing with cold formed members [4].…”

For the past few decades, substantial progress has been made in material properties and construction methodology, which demands in need of development of stronger and lighter members in structural steel applications. The demands of increase in strength and reduction in weight of sections leads to development of structures which are slender and also stability plays a major role in design. The main goal of this study is to develop and investigate the performance of build-up steel I beam sections with corrugated webs. This study focuses on analysis of flexural behaviour and failure modes of plain web, rectangular, trapezoidal web and triangular web in beams by experimental investigations using three-point load test and analytical investigations using ANSYS software. From experimental and analytical analysis, triangular corrugated web beam performs better compared to all section. The experimental results obtained are more similar to analytical results obtained by ANSYS software with only slight deviations. The failure modes in both experimental investigation and analytical analysis are similar.

“…The study is focused on the local buckling behaviour of these girders with web openings. Romeijn, Sarkhosh and Hoop in 2009 [5] present a parametric study on steel girders with trapezoidal corrugated webs having cut outs. Finite element analysis (FEA) is used to investigate the effect of cut outs in corrugated webs.…”

The paper presents a study of the transverse bending behaviour of corrugated web beam with and without web openings. Examined steel beams consist of two flanges and a thin triangularly corrugated web, connected by automatic welding. In the literature, the influence of web opening over transverse load carrying capacity was dealt with mostly for steel beams with plane, sinusoidal and trapezoidal corrugated webs, so researches of beams with triangularly corrugated webs were found out to be very limited. A parametric study is carried out for various web slenderness and corrugation densities. A general-purpose finite element analysis software ABAQUS was used. The corrugation densities adopted in this study represent practical geometries, which are commonly used for such structures in building practice. Models with and without web openings were analysed and examined in terms of load-deformation characteristics and ultimate web shear resistance. Recommendations are given for the practical design of corrugated web beams weakened by circular openings.

“…The stability of shear buckling due to thinness is affected by the height and wave form of the web, and local buckling, global buckling, and their coupling take place. Investigations of corrugated web mainly focused on shear buckling behavior and safety, elastic transverse buckling due to bending of corrugated web girder, behavior of fatigue load and improvement of the fatigue life, and so on [7][8][9][10][11][12]. Particularly, the initial imperfection is adequately sensitive to bring about shear buckling, and verification of the buckling performance for the safety becomes a very important factor.…”

Fundamental advantage of using corrugated web girder rather than plate girder reinforced with stiffeners is securing stability against shear buckling of web and unnecessary stiffeners despite the thinner web. Nonetheless, because shear buckling behavior of corrugated web is very complex, the design mechanism for beams and local, global, and interactive buckling problems should be considered in designing of its structural optimization for better economics and reasonableness. Therefore, this paper proposes a mathematical model for minimum weight design of sinusoidal web girder for securing better stability with smooth corrugation and aims at developing its optimum design program. The constraints for the optimum design were composed on the basis of the standards of EN 1993-1-5, DASt-R015, and DIN 18800, and the optimum program was coded in accordance with the standards based on Real-Coded Genetic Algorithms. The genetic operators for the developed program resulted in a stable solution with crossover probability between 12.5 and 50%, and the perturbation vector for outbreeding could obtain the best result with the model being applied of feasible design variable space of 20–30%. Additionally, the increase of yield strength resulted in decreased value of the objective function, and it was found through the change of the value of the constraint function that the thickness of web was an important factor in the optimum structural design.
