	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:In this paper the first excursion problem of linear structures subjected to stochastic wind loads is considered. In the space of random variables introduced to model the stochastic excitation, the failure domain of the problem can be expressed as a union of quadratic elementary failure domains. In this paper, the procedures using gradient projection method are proposed for obtaining the design point of the quadratic elementary failure domain, which can provide some insights into enhancing the efficiency of the previously developed simulation method for the concerned first excursion problem. An illustrative example involving an along-wind excited steel building shows the performance of the proposed procedures.
