Embedded part has significant effects on the mechanical performance of tower crane braced frame joint. In this study, a series of experiments with different embedded part parameters are conducted on ultimate bearing capacity, load-displacement relationship, load-strain relationship, failure mode, and failure mechanism. Finite element models are established by the ABAQUS software and compared with the experiment results to verify rationality and credibility of the models. The present experimental study and finite element model analysis focus on the effects of anchor length, anchor width, and endplate area. The research results show that embedded part is pulled out of braced frame joint without plastic deformation, and local stress distribution of braced frame joint is complex with tension, bending, and shear load. The braced frame joint is severely strained and cracked with ultimate bearing capacity. Influence of embedded part parameters on mechanical performance of braced frame joint decreases in the order of anchor length, endplate area, and anchor width. The embedded part parameters have no influence on failure mode but affect the failure mechanism. Ultimate bearing capacity of embedded part is about four times the cracking bearing capacity, and an effective approach to improve ultimate bearing capacity is increasing anchor length. The research results can provide a better understanding of the sensitivity of mechanical and cracking behaviors of tower crane braced frame joint with different embedded part parameters.

“…Loading protocol of SAC (ASTM, American Society for Testing and Materials 2006) as is depicted in Figure 7 is used as displacement history in this study. Based on previous studies (Wei et al 2017b;Shekastehband, Azaraxsh, and Showkati 2018), the maximum lateral drift is set at 5%. FEMA 350 (FEMA-350 2000) for special moment-resisting frames (SMFs) suggests two drift angles corresponding to strength degradation and ultimate drift angles, which are 0.04 and 0.06, respectively.…”

“…Reviewing experiments on unstiffened SPSW reveals that the aspect ratio of the web plays a dominant role in configuring its seismic performance. Figure 1 Wei et al 2017b, Behbahanifard 2003. As could be seen, for the increasing aspect ratio of the SPSW, there are substantial increases in the displacement ductility and maximum inter-story drift.…”

A novel, simple to apply, and economic buckling restrainer system is introduced for steel plate shear walls. The shear wall panel is restrained by parallel non-welded channel restrainers, which are installed on both sides of the steel panel. A set of experiments were designed to examine improvement in the seismic performance of the shear wall due to the application of the proposed restrainer system. Three 1/4-scale down single-story single-bay steel panel specimens including one panel without and two panels with different number of restainers are subjected to cyclic loading. The behavior of steel panel with and without the restrainers is assessed in terms of initial stiffness, ultimate loading capacity, stiffness/strength degradation, and energy dissipation capacity. The use of the proposed restrainer system significantly improves the energy dissipation capacity of the shear wall and this enhancement is increasing at larger drifts. Employing the proposed restrainer system, there is only a slight increase in the ultimate loading capacity, and at the same time, a significant increase in the initial stiffness of the shear wall. No strength degradation is observed for the range of the drifts up to 5%. A design recommendation for the sizing of the parallel restrainer components is also included.

In this study, tension field inclination angle (α), which forms on thin steel plate of steel plate shear walls, is investigated. For this purpose, nonlinear finite element models of selected experimental steel plate shear wall specimens in literature were created. Afterwards, the results of the nonlinear analyses of finite element models and the results of experimental investigations were compared and a good agreement was attained. After creating and validating the models, the correlation of the inclination angle with different plate parameters such as plate thickness, boundary elements stiffness, width to height ratio of walls were studied. Steel plate shear walls with different aspect ratios were modelled and various boundary element cross sectional areas and plate thicknesses were used. It was observed that inclination angle is not very sensitive to plate thickness and boundary element cross sectional areas, but aspect ratios have an apparent effect on the tension field inclination angle. The analysis results showed that the inclination angle takes almost a constant value above 0.01 drift ratio. Moreover, it is observed that the tension field inclination angle develops mostly between 35°-45°.
