The Relationship

The mechanical properties of low-yield-point (LYP) steel and its advantages as seismic steel are introduced in this paper. The theoretical equations of inelastic shear buckling stress at the pure shear action for the LYP steel are derived from unified theory of plastic buckling. The relationship curve of inelastic shear buckling strength and width-thickness ratio of LYP steel shear wall at the different height-width ratios of plate is given through iteration calculation process. The effectiveness of theoretical equations used for calculating the buckling stress is verified by experimental results.

Near Fault Earthquakes

The response of flexible structures with long period to near-fault earthquakes shows an imposed demand on these structures which exceeds their capacity. Also, the relationship between frequency content of earthquake and the main frequency of structure is a significant parameter to the response of structure. Therefore, the sensitivity of the response of structure to period of pulse and the lack of enough records for near-fault earthquakes with different amounts of period of pulse is the most important challenge of structural analysis. Of all methods for this analysis, proposed model by Agraval was used in this study. To achieve this goal, various ratios of period of pulse to main period of structure ( Tp/ T1) were considered, where the effect of higher modes on estimating displacement demands was assessed. Meanwhile, the distribution of shear forces for 6-, 12-, and 24-story reinforced concrete moment frames with steel shear wall was evaluated. The results showed that maximum displacement and force demands were obtained for different structures with Tp/ T1 = 1. Meanwhile, by increasing the number of stories, the effect of higher modes decreased and structures tended to fluctuate in first mode. Furthermore, the most effect of higher modes was obtained for shear force at the roof ( Vroof) and then base shear force ( Vbase), where displacement of roof ( Uroof) did not have any effect on the period of models.

Steel Shear Wall

Corrugated steel plate shear wall (CSPSW) is one of the lateral resistance systems which consists mainly of steel frame (beam and column) with vertical or horizontal corrugated steel plate connected to the frame by weld, bolts or both. This type of steel shear wall characterized by low cost and short construction time with high strength, ductility, initial stiffness and excellent ability to dissipate energy. The aim of this paper is to evaluate the effect of corrugation angle and its direction on the performance of CSPSW under cyclic loading. The Finite element analysis was employed to achieve the research aim. The FE models were validated with experimental data available in the literature. Results reveal that the corrugation angle has a clear influence on initial stiffness, strength, ductility, and energy dissipation of CSPSW. The optimum performance of CSPSW can be obtained with angles of 30o for CSPSW with vertical corrugation and 20o for CSPSW with horizontal corrugation. The use of CSPSW with vertical corrugation provides higher strength, stiffness, and ductility compared to CSPSW with horizontal corrugation. Therefore, it is recommended to use CSPSW with vertical corrugation.

Minimum Stress

A thin rectangular steel wall in a steel shear wall structure always simultaneously sustains the lateral load and the gravity load. The gravity load can affect the shear strength of a steel shear wall. However, this effect is not considered in most of the research and standards, which may lead to potential danger in practice. From the previous study of the authors, the shear strength reduction was not only influenced by the load magnitude but also by the vertical stress distribution. For a simply-supported thick square wall, i.e. width to thickness ratio smaller than 100, the stress distribution can be accurately described in a cosine form. However, for a thin wall under compression and in-plane bending, the cosine distribution will largely overestimate the vertical stress, especially when the walls enter the post-buckling condition. To narrow the knowledge gap, this paper proposed a vertical stress distribution in a three-segment form, i.e. in both edge-segments, a combination of linear and cosine functions from the edge stresses to the minimum stress, while in the middle segment, the stress distribution is constant and equal to the minimum stress. Two strategies, i.e. effective width method and Bedair’s method, are chosen to determine the width of the edge portion. A finite element model (FEM) is developed to evaluate the proposed distribution. The FEM has been verified using the results of our own experiments and tests done by Zaraś et al. The results show that the proposed three-segment stress distribution can well describe the behavior of thin walls of different slendernesses and stress gradients. The cosine distribution obtained from theoretical solution and the effective width model by Bedair are also discussed.

Shear behavior is one of the most important mechanical characteristics that contributes to the performance and appearance of woven fabrics. Because of anisotropy, shear properties of woven fabric are tested in various directions. This research is focused on the experimental study of shear properties of plain woven fabric when shear force acts on specimens that are cut at different angles to the direction of the weft. Tests were conducted on woven fabric specimens that were fastened in two parallel clamps of the tensile tester. Five cotton woven fabrics of different weft density and of the same warp density were used. The research results show a very high degree of correlation between shear force and its axial component for all directions of the cutting specimen, and likewise between the relative extension of the diagonal of the specimen and the vertical displacement of the specimen. The initial shear modulus of woven fabrics was determined experimentally and theoretically.
