Evaluation of Performance of Concrete Buildings Damaged by the September 19, 1985 Mexico Earthquake
As a part of a general evaluation of the structural behavior of buildings during the 1985 earthquake in Mexico City, a detailed study of 8 damaged concrete buildings has been performed. The paper contains a general description of the buildings, of their damage and of its possible causes. An approximate method of evaluation of seismic strength is proposed and applied to the eight buildings. General conclusions about the causes of damage and about changes needed in the design practice are proposed.
This paper presents the story of a painting of the “Virgin of the Holy Hand”, which the people of Guayaquil were very devoted for four centuries, until 1902, when a major fire in the city reduced it to ashes. Around the image were generated stories, legends, devotions, etc. that the city lost in that fire. Despite this, we are currently trying to rescue the history of the image, as discussed in this article of a more historical point of view, which makes use of Spanish and American sources. This is a historical study, chronologically exposed. After a brief introduction, the history of the image is analyzed from its creation in the sixteenth century to its disappearance in 1902, and the efforts made to rescue it in the last century. The paper ends with a brief conclusion.
