Abstract

Foundations under machinery that produce impact loads, such as in forge shops, are major industrial sources of wave propagation in soil. The resulting vertical soil vibrations may cause dynamic settlements of column footings. Analyzing of a number of case histories shows that dynamic settlements of footings under columns and connected with them exterior walls at forge shops occur relatively slowly when the soil conditions are different from saturated sands. There are other causes of extensive damage of shop exterior walls. For predicting the dynamic settlements from new machine foundations, it is necessary to know expected footing vibrations. These vibrations can be determined using the method for prediction of soil and building vibrations before installation the foundation under machine producing impact loads.

Vibrations of Impact Machine Foundations and Footing Settlements

St. Louis, Missouri

Foundations under machinery that produce impact loads, such as in forge shops, are major industrial sources of wave propagation in soil. The resulting vertical soil vibrations may cause dynamic settlements of column footings. Analyzing of a number of case histories shows that dynamic settlements of footings under columns and connected with them exterior walls at forge shops occur relatively slowly when the soil conditions are different from saturated sands. There are other causes of extensive damage of shop exterior walls. For predicting the dynamic settlements from new machine foundations, it is necessary to know expected footing vibrations.
