Old bridges in Mexico built before the current seismic design regulations, have structural deficiencies. On the other hand, knowledge about the damages caused by seismic effects on bridges and the most appropriate selection ...

On September 19th 2017, Mexico City suffered many human losses and over 1000 buildings were damaged due to a magnitude Mw=7.1 earthquake in Puebla, mainly affecting seismic zones II, IIIa, and IIIb. Out of the 77 collapsed ...

In this work, the possibility of using braces, energy dissipating devices with hysteretic behavior and viscous behavior to reinforce structures with a flexible ground floor is analyzed. The typological structural characteristics ...

During the earthquake of September 19, 2017, with epicenter 12 km southeast of the town of Axichiapan, Morelos and magnitude Mw=7.1, more than 1000 buildings were damaged and 44 of them collapsed. The use of these buildings ...

The first story free of obstacles, open spaced, with natural light and ventilation, is one of the most attractive architectural configurations in buildings for the human use. This first story is usually composed of frame ...

The bridges are structures designed to save topographic accidents (river, canyon, valley, etc.) and are very important for the economic development of the country that allows the exchange of goods and services. The Mexican ...

The use of isolation devices to protect bridges structures against seismic events has a great success around the world. Because of the nature of this devices, the use of them requires analytical methods that accounts for ...

Bridges are structures essential road infrastructure Mexico; would not be possible without them the economic development of the regions. The interruption of its operation would cause significant economic losses. For the ...

Many of the built bridges that are built today have a strong irregularity in stiffness of the substructure, mainly due to the different heights of the batteries. This work was motivated by the increasing use of insulation ...

A study of the structural health of three new prestressed concrete bridges is performed by using ambient vibration measurements. A campaign of ambient vibration measurements during one year is conducted. The study starts ...
