Wind Vibration Reliability Analysis Of Glass Curtain Wall Based On Improved Artificial Bee Colony Algorithm

Through consulting recent research achievement about point supported glass wall domestic and overseas, combining the feature of itself and the application of swarm intelligence algorithms, here the reliability model of wind vibration analysis is established based on structural reliability theory. It is different between the supporting system for the point supported glass curtain wall and general component, they also different in wind reliability analysis method of reliability analysis, the traditional structural reliability function is difficult to apply to dealing with supporting structure system of glass curtain wall, and it is difficult to express the support system function of the glass curtain wall. Therefore we analyzed the model by using improved artificial bee colony algorithm based on information entropy, it is proved that the method is feasible and effective.The main work of this dissertation is as follows:Firstly we introduced the development history and research status of point glass curtain wall. Then the glass curtain wall structure was introduced and analyzed. Then we introduced the basic principle mathematical model of artificial bee colony algorithm. the artificial bee colony algorithm was improved to overcome its own disadvantages. Here introduced information entropy, it can achieve the adaptive control when it search the solution space and overcome the defect such as premature. Then we introduce the character of wind and the wind load of glass curtain wall supporting structure, here we establish point supported glass curtain wall equivalent model through wind vibration analyzing, and deduce the calculation formula, then we alter the formula based on different landscape, height and support modes. Through numerical simulation and compared with the current expression of wind vibration coefficient, we verify the wind vibration coefficient simplified formula is effectiveness. Lastly,. It also provides a reference for the application of practical design. The reliability index and failure probability is calculated based on improved artificial bee colony algorithm, through simulation. It is proved that the method is feasible and effective.Because of the traditional methods in solving the support system reliability of point supported glass curtain wall is insufficient, the information entropy is introduced into artificial bee colony algorithm, then analyzing structure system reliability based on improved artificial bee colony algorithm. Through example analyzing, the method on the precision and speed has more effect than traditional method.
