“…The stiffness, strength, and energy absorption performances of corrugated and perforated SPSWs were investigated numerically by Farzampour et al [8]. Some of the advantages and disadvantages of employment of corrugated and perforated infill plates in terms of structural performance of SPSW systems were demonstrated.…”

“…where Pcr corresponds to the critical buckling load of the shell specimen; E, the Young's modulus; R, the radius; t, the thickness; and L, the length. It has been previously reported that the geometric parameters-including mostly the above parameters-significantly affect the buckling strength of shells [1,24,25]. Further, in this GEP model, the number of genes was considered as 2, mutation rate as 0.044, inversion rate as 0. output in this study.…”

“…For these cylindrical shells subjected compressive loads, the buckling limit state needs to be considered because it has been reported that buckling is the primary limit state for cylindrical shells compared to plates and columns. Furthermore, the stability of shell structures is also governed by the buckling behavior [1,2]. Hence, many researchers have studied this behavior to determine the most accurate capacity of cylindrical shells under compressive loads.…”

Determination of buckling behavior of shell structures has long been identified as a challenging task. This is largely because the buckling behavior is masked by local large deformations, which occur once the critical load is reached. This research proposes a novel technique to accurately predict the buckling load of imperfect cylindrical shells using gene expression programming (GEP), which is an evolutionary artificial intelligence method. An existing experimental data bank was employed for training and testing the program, and the obtained buckling load of shell structures were accordingly verified. From the results, it is concluded that GEP is a promising and reliable method to determine the buckling load of shell structures subjected to axial compression.Sažetak: Definiranje ponašanja pri izvijanju odavno je identificirano kao izazovan zadatak pri izučavanju plošnih konstrukcija. Razlog tomu je činjenica da lokalne velike deformacije nastaju nakon dosezanja kritičnog opterećenja pa je opće ponašanje pri izvijanju prikriveno tim deformacijama. Ovo istraživanje predlaže novi pristup za precizno određivanje sile pri izvijanju kod nesavršenih cilindričnih ljuski, primjenom programiranja genetičkim izrazom (GEP), evolucijske metode umjetne inteligencije. Za učenje i testiranje programa primijenjena je postojeća eksperimentalna baza podataka te je predložen izraz za silu pri izvijanju plošnih konstrukcija, koji je sukladno tome i verificiran. Zaključeno je da je GEP obećavajuća i pouzdana metoda za određivanje sile izvijanja kod osno naprezanih plošnih konstrukcija.

“…Therefore, the authors do not recommend the use of circular holes in corrugated sheets for a cold-formed steel shear wall to provide resilience. Faramarzpour and Laman Jeffrey (2015) examined the behavior of corrugated steel shear wall with opening. This study has been numerically compared corrugated and simple steel plate, with and without opening.…”

The steel shear wall system has been considered as a structural system over the past few decades. This issue deals with wind and earthquake lateral forces due to its hardness, loading capacity and plasticity. This type of the system, with the use of external hardness resulting from the geometric shape of the waves, has better buckling strength than a hardened and smooth mood. In this paper, at first, the experimental test is validated with ABAQUS software which simple rectangular steel plate was used in the shear wall so that both cyclic and monotonic loading conditions have been compared Since then the concrete shear wall behavior has been evaluated using sinusoidal steel plates with different variables such as concrete compressive strength 25 and 35 MPa thickness of corrugated plate including 0.8 and 1 mm and wave height 25 and 50 mm are considered as variables. The interaction between concrete and steel is applied using Tie and the base of the wall is fixed. Moreover, the sample is loaded in accordance with the ATC24 instruction with a displacement of 85 mm using displacement/rotation by activating U1 direction as lateral load. Generally, eight different models have been evaluated and the pushover graphs are compared based on thickness and concrete strength. The results show that increasing the thickness, the wave height and the compressive strength of the concrete leads to increased resistance and ductility.
