PROPOSED CONSIDERA TIONSFOR REVISION OF EBCS-8: 1995FOR CONSERVATIVE SEISMIC ZONING AND STRINGENT REQUIREMENTS FOR TORSIONALLY IRREGULAR BUILDINGS

Abstract

There is a significant variation in seismic zoning
adopted in Ethiopia for urban areas between the
seismic building code [1]' and those reported in
other research publications. F.urther, it is also
believed that the torsional loads recommended by
the current seismic building code to account for
accidental torsion are not conservative,.enough for
a seismically active country such as Ethiopia where
th,re is inadequate quality control in construction
practices. This paper deals with proposals for
implementing a conservative seismic zoning for
urban areas such as Addis Ababa and
implementing a more stringent torsional load
requirements in the current Ethiopian seismic
building code [2J.
