“…Contrary to [11], the results confirm that for cylinders with an axial crack and a length-to-axial length of the cylinder ranging from 0 -0.15, a change in the crack length (i.e., increasing the ratio of crack length-to-axial length of the cylinder, 2a/L) will cause a considerable reduction in the load carrying capacity of the cylinders. The crack length extending by about 5% of the cylinder axial length will cause a reduction of approximately 10% in the load carrying capacity of the cylinder.…”

“…This result appears to be in agreement with published work in the open literature [6][7][8], i.e., load carrying capacity of the cylindrical shell structure reduces as the axial crack length increases. In addition, the experimental data set complements the work of Shariati et al [11] and widens its scope by catering for the axial crack length-to-axial length of the cylinder within the range of 0.05 to 0.2. From the experimental results presented in this paper, it is obvious that increasing the axial crack length-to-axial length of the cylinder by 10% (i.e., 0.1) causes a reasonable reduction in the buckling load of the cylinder, a reduction of about 26% in the load carrying capacity, while increasing the crack length-to-axial length of the cylinder by 15% (i.e., 0.15) will produce a reduction of about 31% in the load carrying capacity.…”

“…Two types of cracks were analysed; (i) through crack, and (ii) thumbnail crack. In Shariati et al [11], the ABAQUS finite element code was used to carry out a linear and non-linear analysis on the effect of the crack position, crack orientation and crack length on the buckling and post-buckling behaviour of thick and long cracked steel cylindrical shells with a radius-to-thickness ratio, R/t = 10.5, the axial length-to-radius ratio, L/R, ranging from 4.76 to 11.9 and the crack length-tocircumference of the cylinder ratio, a/2R, are 0.2, 0.3 and 0.4. The finite element results were benchmarked by conducting several experimental buckling tests.…”

“…While, Vaziri and Estekanchi [10], cover cracked cylinders under combined loading. Furthermore, a numerical and experimental investigation of cracked steel cylindrical shells subjected to combined loading can also be found in [11]. Recent experimental studies on the buckling behaviour of cracked steel cylinders subjected to axial compression were only presented in [12][13][14].…”

“…Also, it was revealed that the load carrying capacity of the axially compressed cylinder could be affected by the orientation of the crack, with the circumferential crack (0) producing the lowest reduction while the angling crack (45) results in the largest reduction. The motivation for the present work originates from the conclusion of Shariati et al [11], where it was reported that for cylindrical shells with axial cracks, the change in crack length and increasing the crack length-to-circumference of the cylinder ratio, has minor effects on the buckling load of the cylinder. The aim of this paper is to examine the effect of increasing the ratio of the axial crack length to the cylinder axial length (i.e., 2a/L ranging from 0 -0.15) on the load carrying capacity of the axially compressed cylinder.…”

This paper studies the buckling behaviour of cylindrical shell structures with an axial crack subjected to axial compression. This work is both experimental and theoretical. The results of the test on four laboratory scale mild steel cylinders and the associated theoretical estimation of the buckling loads for a cylinder with no cracks are provided. The geometry parameters of the cylinder were assumed as follows: the radius-to-thickness ratio (R/t) was taken as 100, while the axial length-to-thickness ratio L/R, was 2.2. The nominal thickness of the specimen was 0.5 mm. Cylinders had an axial crack introduced to a fraction of the cylinder's axial length. The magnitude of the crack length-to-cylinder axial length varies between 0 and 0.15. All four cylinders were subjected to axial compression using an instron universal testing machine. The experimental results reveal that the load carrying capacity of the cylindrical shells is strongly dependent on the crack length, i.e., increasing the crack length leads to a decrease in the buckling load of the cylindrical shells. As an example, the cylinder with an axial crack extending by 15% of its axial length will lead to an approximate reduction of 31% in the load carrying capacity of the shell.

Summary In spite of existing comprehensive studies on the behavior of steel plate shear wall (SPSW), some aspects of the SPSW have remained unknown, yet. One of the important aspects that is unknown is the crack effect on the SPSW behavior in linear and nonlinear zones. Some experimental studies have been reported that SPSWs were fractured due to crack propagation. Therefore, the crack effect on the behavior of SPSW should be accounted in considering of SPSW behavior. Although the effect of crack on the thin SPSW has been investigated to a limited extent numerically, stiffened SPSPW, especially diagonally stiffened SPSW, has not been studied. In doing so, in this paper, the effect of crack effect on the behavior of diagonally stiffened SPSWs is studied parametrically and numerically. Numerical results showed that stiffened walls exhibit better behavior in the presence of crack compared with SPSW in both elastic and inelastic zones. Because crack propagates in nonlinear zone, it has not effective on elastic behavior of diagonally stiffened SPSW. The effect of crack was also presented as mathematical equations to estimate load–displacement curve that are in agreement with the finite element results especially for wall thinker stiffeners.
