Abstract:The load capacity design condition, variable thickness ratio,  internal force analysis, punching calculation, construction requirement and economical index control etc. for variable thickness slab-column structure were summarized. Variable thickness slab-column structure in the basement of a large market with 10.8m×10.8m span was designed. The thickness of slab belt in the axis was increased to form the intersection strengthened slab belt and better technical-economical index was obtained.

Keywords:long span; variable thickness slab-column structure; load capacity design condition;  variable thickness ratio;
