Practical study of structural reliability design based on design value method
At present,the design of structures mainly adopts the probability based partial coefficient method.However,with the improvement of material strength,construction technology,equipment performance,and changes in load effects,this method lacks flexibility,universality,and reliability control accuracy due to the fixed values of partial coefficients in the application process.For this reason,the design value method is proposed internationally.The method can fundamentally solve the defects of the current design method,but it still lacks sufficient engineering practicability and has not been fully promoted.In view of this,according to the current engineering design habits,a practical design expression based on the design value method is established on the basis of the structure reliability theory and the current design value method,and the optimal sensitivity coefficients are selected for the new design expressions in combination with engineering practice,so as to establish the application research theory of the new practical design value method.The results show that the new practical design value method improves the reliability control accuracy and practicality in engineering applications.
