GOMEZ CANO, JUAN CAMILO  e  FARBIARZ FARBIARZ, JOSEF. STRUCTURAL DESIGN PROCEDURES BASED ON NSR-98 ERRORS, EXAMPLES AND UPDATE PROPOSALS. Dyna rev.fac.nac.minas [online]. 2005, vol.72, n.147, pp.7-21. ISSN 0012-7353.

In this work, Title C, and of some aspects related to it in Titles A and B, of the Colombian standards for earthquake resistant design and construction, NSR-98 (Law 400 of 1997 and their regulation ordinances) are reviewed and studied. Title C of NSR-98 is dedicated to the design and construction of structures of structural concrete,. Decree 1400 of 1984 regulated the first Colombian code for earthquake resistant constructions, the Colombian Earthquake Resistant Design and Construction Code (Código Colombiano de Construcciones Sismo Resistentes), CCCSR-84, based on the work of Committee AIS-100 of the Colombian Association of Seismic Engineering, AIS, and created by presidential order soon after important damages caused in Popayán by the earthquake of 1983. This code, employed for more than 14 years, was updated by AIS-100- 97, a AIS 100 committee document, which became Law 400 of 1997, regulated by decrees 33 of 1998, 34 of 1999, 2809 of 2000 and 52 of 2002. To place the work into perspective, main differences between the NSR-98 and the CCCSR-84 are iodentified, highlighting the new aspects introduced with the update and detailing the specific changes that the new version brought to the Title C, dedicated to the design and construction of structures of structural concrete.
