IS 13827 : 1993 Improving earthquake resistance of earthen buildings - Guidelines

1 Scope

1.1 The guidelines covered in this standard deal with the designand construction aspects for improving earthquake resistance ofearthen houses, without the use of stabilizers, such as cement,lime, asphalt, admixtures, etc.

1.2 The provisions of this standard are applicable for seismiczones III, IV and V. No special provisions are considered necessaryin zones I and 11 (see IS 1893 : 1984 for seismic zones).

Note 1 Earthen buildings are inherently weak against water andearthquakes, and should preferably be avoided in flood prone, highrainfall areas and seismic zones IV and V.

Note 2 Attention is hereby drawn to the fact that earthenconstruction as dealt with herein will neither qua]ify asengineered construction nor totally free from collapse in severeseismic intensities VIII and lX on MMI scale. However, inclusion ofspecial design and construction features as recommended in thisstandard will raise their weather and seismic resistanceappreciably reducing greatly the chances of collapse even in suchseismic intensities.
