Abstract:In this paper, the consideration of system selection of long-span steel structure, and the structural analysis and design optimization of Lamellar-Kiewitt suspend-dome were studied. The first part of this paper summarized and classified all kinds of the long-span spatial steel structure system, and their main structural features, development, and application, advantages, and disadvantages were briefly introduced. Selecting the feasible system was considered based on architecture, structure, economy, and buildability index. The Lamella-Kiewitt suspend-dome is selected as the roof structure, and the static performance of the structure is obtained by nonlinear geometric static analysis, the eigenvalue analysis is carried out by subspace iteration method, and the response spectrum analysis is adopted for dynamic analysis of the structure. The axial stress in cable-strut, the overall deflection of the roof structure, and the natural frequency were satisfied with the Chinese design code. The structural optimization of the roof structure is studied under the various rise-to-span ratio, strut-height, and single-layer reticulated shell types. Analyses and optimization of suspend-dome in the paper were conducted with finite element software Midas Gen. From the result of optimization show that the total steel consumption of Lamella-Kiewitt single-layer suspend-dome structure with four hoop cables has a good economy. The study of this paper can provide a reference for the construction of a similar structure in the future. | |||

Abstract:The Brazier effect in thin-walled angle beam subjected to pure bending is investigated. The derivation using energy method is presented to predict the maximum bending moment and section deformation. Both numerical analysis and experimental results were used to show the validity of the proposed method. Numerical results show that the boundary condition can influence the results due to the end effect, when the length of angle beam goes up to 30 times as the length of beam side, the influence tend to be negligible and the results show great agreements with proposed method with about 5%-15% error. It was observed during the experiment that the collapse of structure is governed by either of Brazier flattening, ridge-line buckling or load-point crippling. When the collapse is governed by Brazier flattening, experiment results are generally 20 percent higher compared with theoretical analysis results, which is a reasonable accuracy in consideration of end effect. . | |||

Abstract:In order to promote the application of angle-steel confined high-strength concrete (ACHC)columns in new construction and reinforcement projects of civil engineering, this paper took the hoop coefficient, strength grade of concrete and yield strength of steel as parameters, 15 angle-steel confined high-strength concrete(ACHC)short columns with a shear span ratio of 1.5 were designed under axial compression. Based on simplified steel constitutive model and confined concrete constitutive model considering hoop effect, the finite element simulation analysis on them was carried out, by comparing with the experimental data the rationality of finite element modeling is verified. The author investigate the influence for different hoop coefficient, different concrete strength grade and different yield strength of steel to mechanic behavior of ACHC short columns. Considering the hoop effect of batten plate to concrete, the influence factor of the slab is introduced, and the linear relationship between the influence factor and the hoop coefficient is inverted by using 1stopt software. Calculation formula of ultimate bearing capacity of ACHC short columns under axial compression is gotten and design method and design suggestion of this kind of short column is put forward. The results show that hoop coefficient for influence of bearing capacity and ductility of short column is more significantly than other parameters, which can lay a foundation for application of this kind of short columns in new construction and reconstruction projects. | |||

Abstract:The dynamic response of a bridge under the effect of moving vehicles has been studied in decades. In this paper, using matrix transformation via the Newmark-β Method for partial differential equations, an extended solution for multi-vehicle crossing a bridge is proposed and validated with previous studies. Firstly, parametric studies for the case of two vehicles crossing the bridge are made. The effect of the vehcile velocity, the distance between vehicles, the weight ratio between the sprung and the unsprung mass of the vehicles, the mass ratio between the vehicle and the bridge, the bridge damping, the spring damping of the vehicles and the elastic parameter of the vehicles are investigated. Finally, a case involving four vehicles and data from a real long concrete bridge is presented. A wide range of the conclusions from the previous parametric study are confirfed again. | |||

Abstract:The performance of concrete-encased CFST column under combined compression and bending is studied in this paper. Concrete-encased CFST (concrete-filled steel tube) has attracted the interests of structural engineers and researchers due its good structural behaviour. A finite element analysis (FEA) model is developed to analyse the behaviour of the composite column, and generally good agreement is achieved between the measured and predicted results in terms of the failure mode, the load-deformation relation and the ultimate load. Typical failure modes, full-range response of load-lateral deflection relation, loading distributions of the inner CFST and the outer RC components, the contact stress between the steel tube and the concrete of the composite columns are analyzed. The influence of slenderness ratio on the composite columns is also investigated. Influence of parameters, such as the strength of concrete and steel, steel ratio of CFST, longitudinal bar ratio and diameter of CFST on the sectional capacity of the concrete-encased CSFT columns is analysed based on the FEA model. | |||

Abstract:This paper is dedicated to the buckling behaviors of strengthened perforated plates under edge shear loading, which is a typical load pattern of steel plates in civil engineering, especially in plate and box girders. The square plates considered each has a centric circular hole and is simply supported on four edges in the out-of-plane direction. Three types of strengthening stiffeners named ringed stiffener (RS), flat stiffener (FSA and FSB) and strip stiffener (SSA, SSB and SSC) are mainly discussed. The finite element method (FEM) has been employed to analyse the elastic and elasto-plastic buckling behavior of unstrengthened and strengthened perforated plates. Results show that most of the strengthened perforated plates behave higher buckling strengths than the unstrengthened ones, while the enhancements in elastic buckling stress and elasto-plastic ultimate strength are closely related to stiffener types as well as plate geometric parameters including plate slenderness ratio and hole diameter to plate width ratio. The critical slenderness ratios of shear loaded strengthened perforated plates, which determine the practical buckling pattern (i.e., elastic or elasto-plastic buckling) of the plates, are also studied. Based on the contrastive analyses of strengthening efficiency considering the influence of stiffener consumption, the most efficient cutout-strengthening methods for shear loaded perforated square plates with different slenderness ratios and circular hole diameter to plate width ratios are preliminarily identified. | |||

Abstract:Based on the experimental results of a stay cable model incorporated with a small size MR damper, a model consisting of the modified Bouc-Wen model in series with a standard model of a linear solid is proposed to predict the MR damper response attached to the stay cable. Using the experimental results of the stay cable with the MR damper and performance testing of the MR damper, dynamic properties of MR damper with constant current input coupled with stay cable is firstly studied. To carry out the semi-active vibration control of the stay cable model by using MR damper, dynamic analysis is carried out to predict the behavior of the MR damper with a continuously varied applied voltage to expect the achieved semi-active MR damper force. Dynamic analysis results is validated well by the numerical simulations of the measured experimental data. . | |||

Abstract:This paper presents the study on the behavior of composite frames with circular concrete filled steel tubular (CFST) columns to steel beam. Six composite frames were tested under a constant axial load on the CFST columns and a lateral cyclic load on the frame. Each frame specimen consisted of two CFST columns and a steel beam to represent an interior frame in a building. A finite element analysis (FEA) model was developed to investigate the behavior of the composite frame. The results obtained from the FEA model were verified against those experimental results. Detailed analysis was carried out on longitudinal stress in steel beams, axial stress distribution in concrete, concrete stress along the column height and at the connection panel. Parametric studies were conducted to investigate the influence of axial load level, beam-to-column linear stiffness ratio on the structural behavior of composite frames. A simplified hysteretic lateral load versus lateral displacement model was proposed for such composite frames. | |||

Abstract:A finite element method (FEM) study is conducted herein to simulate the cyclic behaviour of steel beam to concrete filled steel tubular (CFST) column joints under a constant axial load and a cyclically increasing lateral load to simulate forces. The finite element program ABAQUS was used for the analysis. A plastic damage model for concrete and elasto-plastic model for steel were used to simulate the damage and degradation of the materials. Eight specimens of steel beam to square concrete-filled steel tubular (CFST) joints using an external ring were tested to assess the hysteretic behaviour under combined constant axial load and cyclical lateral load. The axial load level of the CFST column, width of connection stiffening ring were considered as influential experimental parameters to the seismic behaviour of the specimens. The lateral load (P) versus lateral deformation (Δ) hysteretic curves showed no obvious strength deterioration and stiffness degradation. It can be concluded that the joints exhibited good seismic performance. It was also found that the axial load level had an influential effect on both the strength and seismic behaviour of the joints. The lateral ultimate strength of the joints reduced and the displacement ductility and the energy dissipation capacity decreased with an increased axial load level. Furthermore, the failure mode of the joints changed from a plastic hinge in the beam end to fracture in the ring zone. The eight specimens tested were analysed using a FEM model. The results obtained from the FEM model showed reasonable agreement with the experimental results. | |||
