Mine-Induced Seismic Events and Its Effect on Nearby Settlements in South Africa
Abstract eng: Recent seismic activities have revealed certain flaws in building designs in South Africa. Seismic activities in Southern Africa are predominantly mine-induced. The characteristics of these activities are distinctly different from tectonic activities and its effects on buildings and structures are different. Structural failures in the seismic event of 9 March 2005 at Stilfontein near Klerksdorp have been investigated as a case study. This paper describes the characteristics of seismic events in Southern Africa based on recorded seismic events. A field study of the Stilfontein 2005 event in South Africa has shown that the general orientation of buildings as north facing is a major factor in failures during medium seismic events. Typical failure modes and causes of failure are discussed. Design and detailing recommendations are proposed to avoid failures of similar nature in buildings and other infrastructure.
