Abstract

This paper discusses the causes of damage of a broadcasting transmission station suffered from settlement cracks. The station buildings were low-rise reinforced concrete structures with isolated footings founded on alluvial deposit. Investigations revealed that the main causes of the observed nonuniform settlement were the existence of silt pockets below some footings, and the shrinkage of clayey soils due to dryness of the subsoil after ceasing the cultivation of land and using it as construction site. Rehabilitation scheme included structural repair of the cracked columns, beams and walls, and injection grouting of the foundation soil beneath the settled columns.

Damage of a Broadcasting Station Due to Shrinkage of Soil

St. Louis, Missouri

This paper discusses the causes of damage of a broadcasting transmission station suffered from settlement cracks. The station buildings were low-rise reinforced concrete structures with isolated footings founded on alluvial deposit. Investigations revealed that the main causes of the observed nonuniform settlement were the existence of silt pockets below some footings, and the shrinkage of clayey soils due to dryness of the subsoil after ceasing the cultivation of land and using it as construction site. Rehabilitation scheme included structural repair of the cracked columns, beams and walls, and injection grouting of the foundation soil beneath the settled columns.
