Code-based earthquake engineering is on the verge of getting simpler, thanks to the National Earthquake Hazards Reduction Program’s recommendation to replace the traditional seismic hazards maps with an improved seismic hazards database. 

Team building (W)rapper’s ribboned exoskeleton, which is not self-supporting until it is done, relies on falsework for stability during steel erection.

A magnitude 7.1 temblor struck northeast of Los Angeles on Friday, July 5 at 8:19 p.m., a day after a 6.4 magnitude rocked the same area, knocking out power to thousands and prompting questions on proper calibration of a recently introduced earthquake early-warning system.

Raised in Venezuela, U.S. citizen Andres Lepage considers his adopted homeland the “best country in the world.”

The magnitudes 7.0 and 5.7 earthquakes that struck Anchorage, Alaska, on Nov. 30 shook buildings and shattered highways, but caused limited structural damage and no reported loss of life, mostly due to the depth and location of the quake’s epicenter, as well as the city and state’s stringent building requirements.

To reduce seismic risk to new tall buildings, San Francisco should develop regulations to address foundation and geotechnical issues.
