Study on Large Air Cooled Thermal Power Structural Wind Properties under Different Wind-Break Wall Forms

Abstract:

Air cooled thermal power structure is composed of spatial steel truss and steel-concrete tubular columns. Permeable “A” shape structure and wind-break wall are installed on its top. The wind load in the wind-break wall has great effect on its lower part. The structural wind parameters is not clearly stipulated in current load code. To solve the problems of wind parameter value in design and effectively evaluate the influence on wind-break wall form to the structural wind-resistant properties, three different wind-break wall forms are presented. Wind properties on an actual air cooled thermal power structure under three different wind–break wall forms are simulated with FLUENT software. Wind pressure law on “A” type structure and wind-break wall under different wind-break wall forms and at different wind direction angles is studied. Every division section shape coefficient of wind-break wall and “A” type structure under different conditions is obtained. The wind presure distribution law and the most reasonable wind-break wall form is obtained.
