Strategy to increase distortional rigidity of crane box girder: Staggered truss diaphragm SCIE
期刊论文 | 2023 , 86 (4) , 461-472 | STRUCTURAL ENGINEERING AND MECHANICS
Abstract&Keyword Cite

Abstract :

This paper proposes a novel method for increasing the distortional frame rigidity of off-rail box girder bridges for cranes by reinforcing the diaphragm with staggered truss. The study starts by using the Matrix Displacement Method to determine the shear angle of the staggered truss diaphragm under two assumptions: hinge joint and rigid joint. To obtain closed -form solutions for the transversal and longitudinal deformations and warping stress of the crane girder, the study employs the Initial Parameter Method and considers the compatibility of shear deformation at joints between the diaphragms and the girder. The theoretical solutions are validated through finite element analysis, which also confirms that the hinge-joint assumption accurately represents the shear angle of the staggered truss diaphragm in girder distortion. Additionally, the study conducts extensive parameter analyses to examine the impact of staggered truss dimensions on distortional stress and deformation. Furthermore, the study compares the distortional warping stresses of crane girders reinforced with staggered truss diaphragms and those reinforced with perforated ones, emphasizing the importance of incorporating stagger truss in diaphragms. Overall, this paper provides a thorough evaluation of the proposed approach's effectiveness in enhancing the distortional frame rigidity of off-rail box girder bridges for cranes. The findings offer valuable insights into the design and reinforcement of diaphragms using staggered truss to enhance the structural performance of crane girders.

Seismic performance of joint for H-beam to CFST column with field-bolted flange-splicing SCIE
期刊论文 | 2022 , 196 | JOURNAL OF CONSTRUCTIONAL STEEL RESEARCH
WoS CC Cited Count: 8
Abstract&Keyword Cite

Abstract :

A novel shop-welded joint for H-beam to concrete-filled steel tubular column with field-bolted flange splicing used in prefabricated steel structure is proposed. Four full-scale specimens were tested under cyclic loads, and the effects of bolt diameter, beam flange cover plate, widened beam flange at the end, and the flange thickness on the seismic performance of joints were studied by experiments and numerical simulation. The seismic performance of the shop-welded joint is compared to that of traditional welded joints. According to the results, the beam flange thickened by welding cover plate and widened by welding plate at the beam end can improve the yield resistance, ultimate resistance, stiffness, ductility, and energy dissipation capacity of the joint, while the bolt diameter and the flange thickness did not make significant influences. The shop-welded joints could be regarded as rigid. Adding cover plate, widening beam flange, or increasing column base flange thickness can effectively reduce the beam end stress and avoid brittle failure of welds under rare earthquakes. Simplified formulas for the yield and ultimate loads of the shop-welded joint were proposed.

Seismic performance of bolted connection between H-section beam and SST column welded with inclined braces SCIE
期刊论文 | 2022 , 61 | JOURNAL OF BUILDING ENGINEERING
Abstract&Keyword Cite

Abstract :

To improve the construction efficiency and achieve a rigid connection under design load, an innovative H-section beam-to-square steel tubular (SST) column bolted connection with inclined braces is proposed. The innovative bolted joint can realize bolted assembly between beam and column as well as between column and column, and it exhibits satisfactory stiffness and strength under earthquake with few bolts. Three groups of beam-column bolted joints with different types of inclined braces were designed, and tests and finite element analysis (FEA) were implemented under cyclic loading. The mechanical behaviour, deformation process, failure modes, and energy dissipation of all specimens were observed, and the effect of the type and length of inclined brace on seismic behaviour of joints was analyzed. The results showed that all specimens exhibited satisfactory ductility, plastic deformation capacity and energy-dissipation capacity. All tested joints with inclined braces showed failure mode of severe local buckling of beam section outside the connecting area, and the strength, stiffness and energy dissipation capacity of bolted joints with inclined braces were significantly improved. The joints with an H-shaped brace dissipate more energy than those with a channel brace, particularly when the web of the H-shaped brace is perpendicular to the beam web. Furthermore, the strength, stiffness and energy dissipation capacity of innovative joints with long diagonal braces are higher than those with short diagonal braces. On the basis of the test results and numerical analysis, simplified calculations for the slip resistance, yield resistance and ultimate resistance of the bolted joints with inclined braces are proposed and validated against tests.

Static performance of slidable bolt-assembly truss-to-column connection with oversized bolt holes EI
期刊论文 | 2021 , 176 | Journal of Constructional Steel Research
Abstract&Keyword Cite

Abstract :

The static performance of a slidable bolt-assembly connection between a double-angle truss and square hollow structural section (SHSS) column was studied using experiments and finite-element simulations. Four specimens with different sizes or types of bolt holes on the gusset plate were tested and analyzed. The slip resistance, yield strength, ultimate strength, and failure mechanism of each connection were obtained. The static and seismic performances of the connections were compared with those of a welded connection, bolted-welded connection, and all-bolted fixed connection. The results showed that the ductility of the slidable bolt-assembly connection exceeded a value of 10, which was higher than the values for the other connections, but the slip resistance was the lowest. The slip resistance of the bolt-assembly connection under a static load was larger than that under a seismic load. The ultimate strength of the bolt-assembly connection was equal to that of the welded connection, and the stiffness was almost the same as that of the welded connection before the slip. The ultimate strengths of the slidable bolt-assembly connections were almost the same under static and cyclic loads. The slip distance increased by 23 mm when the bolt hole diameter was increased by 2 mm. However, the dimensions and shapes of the bolt holes on the gusset plate only had slight effects on the slip resistance, yield strength, and ultimate strength of the joint. A load-bearing model and formulas for calculating the various strengths of the slidable bolt-assembly connection were proposed. © 2020 Elsevier Ltd

Bearing capacity of H-section beam wrapped with ceramsite concrete SCIE

WoS CC Cited Count: 2
Abstract&Keyword Cite

Abstract :

In this study, an H-section steel beam with circular holes in a web wrapped with ceramsite concrete (SBWCC) was studied. Static load-bearing capacity tests and finite element analysis were performed on two groups of specimens with different sections. The H-section steel and wrapped ceramsite concrete were well bonded. The load-bearing capacity of the SBWCC was 10% larger than that of the pure H-section steel beam without holes in the web, except for its dead weight. The stiffness of the SBWCC was slightly larger than that of the pure H-section steel beam without holes. The wrapped ceramsite concrete avoided the elastic local instability of the steel beam flange and web. Based on the finite element model verified by experiments, the influences of hole diameter, hole spacing, and U-shaped stirrups on the flexural capacity of the specimens were analyzed. The formulas for the load-bearing capacities and short-term stiffness of the SBWCC were proposed and verified by tests and finite element analysis.
