A Study to Reduce the Inter-story Drifts of Steel Moment Frames Subjected to Seismic Load
Procedia Engineering, 2011 AbstractAn optimal drift design model for the steel moment frames under the seismic load is presented. The objective function of the proposed drift design model is to minimize the differences of the inter-story drifts so that the interstory drifts of the structure could be reduced.

Seismic vulnerability analysis of steel buildings in Bogotá, Colombia [PDF]
, 2012 A number of mid-height steel buildings have been erected recently in Bogotá. Their seismic risk might be high, given the new microzonation of Bogotá and the lack of previous studies; remarkably, the response reduction factors were commonly obtained from ...
