Simple method for calculating base size of chemical tower foundation with circular baseQu Xin(Shanxi Taihua Chemical Industry Design Co.Ltd., Taiyuan 030021, China)

Abstract:Based on GBJ135—90 Code for Design of Domineering Structures, combined with the practice experience in design, through analyzing and deducing to the formula, a simple caculating formula of minimum radius about chemical tower foundation with circular base is obtained. The diagram is made at the same time.An easy and directly method for calculating the base size of chemical tower foundation with circular base is derived, it is calculated accurately with this method, avoiding the complicated calculation.

Keywords:chemical tower foundation; circular foundation base; size of foundation base
