02 Sep 2009 | Notes | Contributor(s): Louis Bergeron

Engineers design self-righting buildings that survive earthquake test in style. Stanford engineers and others create a structural design that lets buildings rock during earthquakes, then pull themselves into plumb when the shaking stops, confining damage to replaceable steel "fuses".

Mitigation of Collapse Risk in Vulnerable Concrete Buildings

30 Jul 2009 | Publications | Contributor(s): Lisa Matchulat

This study investigates the collapse risk of reinforced concrete building columns constructed prior to the mid-1970's, subjected to cyclic lateral loading. These columns have reinforcement details deemed inadequate by modern seismic design standards, and as such are vulnerable to collapse....

Comparative response assessment of minimally compliant low-rise conventional and base-isolated steel braced frames

29 Jul 2009 | Publications | Contributor(s): Emrah Erduran, Nhan Dinh Dao, Keri L Ryan

In this study, the multi-intensity seismic response of code-designed conventional and base-isolatedsteel frame buildings is evaluated using non-linear response history analysis. The results of hazardand structural response analysis for three-story braced frame buildings are presented in this...

Analytical and Experimental Study of Seismic Performance of Reinforced Concrete Frames Infilled with Masonry Walls

29 Jul 2009 | Publications | Contributor(s): Andreas Stavridis

This dissertation describes the experiment conducted on the first shake-table specimen at UCSD, and also the experiments conducted at the University of Colorado.

Project: Experimental and Analytical Investigation of Nonrectangular Walls Under Multidirectional Loads

28 Jul 2009 | Series | Contributor(s): , ,

Previous laboratory testing of T-shaped walls loaded uniaxially along the direction of the stem of the T has indicated that these walls can be detailed using methods similar to those used for rectangular walls. However, multidirectional loading of these walls has not been carried out at large...
