Research On The Static Behavior And Earthquake Response Of Storaage Tank With Latticed Shell

As the industrial blood, oil has great influence on the world economy. At present, humanity's reliance on oil is unable to be substituted by any other energy sources, all countries therefore increased strategic petroleum reserves. From the perspective of tank design, construction and usage, building large capacity storage tank can save steel, reduce floor space, easy operation and management and decrease investments, to build large capacity storage tank is the inevitable trend of development. But tanks have been built are all starting from improving the performance of steel to make tank to the large-scale development, the structure form hasn't been changed. In 2009, Wenfu Zhang put forward a new tank structure——storage tank with latticed shell (STLS), it can make full use of latticed shell tensile strength and its good flexural performance, effectively reduce thickness of bottom plate and tank shell, and reduce cost, have the unique and beautiful appearance, good visual effect, etc.This paper will study on the static behavior and earthquake response of STLS by using ADINA finite element software, and the main work is as follows:1.To verify total tank model and 1/4 tank model's rationality.2.To change parameter of STLS, and research influence of parameter on its static behavior.3.To optimize the 15×10~4m~3 and 30×10~4m~3 STLS, and analyze their static behavior.4.To design 30×10~4m~3 common storage tank by the variable point method, and compromise the 15×10~4m~3 and 30×10~4m~3 common storage tank respectively with the 15×104 m3 and 30×10~4m~3 STLS on economic.5.To study on natural vibration characteristic of common storage tank and STLS under different conditions, comparative analyze the difference of the two type of tanks, and study the influences of the parameters on natural vibration.6.To study on the earthquake response of the optimized 15×10~4m~3 STLS under 4 kinds of earthquake waves.
