Earthquake resistance of loadbearing brickwork structures

Abstract

Unreinforced loadbearing brickwork is a cost effective alternative to reinforced concrete frame structures in low rise residential building such as two to three storey houses, hostel buildings and hotels. For its widespread use, it is necessary to show that such structures would be safe in earthquakes that can be expected. This is because historical records show that earthquakes have occurred around Sri Lanka from time to time. In this paper, an earthquake design method that can be used for loadbearing brickwork structures is highlighted. The values that can be used for design parameters are also given. An example is presented to show the calculation method and the performance of loadbearing brickwork in actual structures. The additional precautions that can be taken in loadbearing brickwork structures constructed in Sri Lanka are also highlighted.
