The Cripple Wall: A Forensic Playbook
How investigators reconstruct the failure sequence when short wood-frame walls beneath raised foundations give way during lateral shaking.
A longitudinal look at the soft-story retrofit ordinances that followed the 1994 earthquake, and which engineering assumptions held up under subsequent tremors.

Insurers and adjusters rarely agree on what depreciation should apply to a storm-damaged roof. Here is how the math actually works — and where it breaks down.
Roughly 13,500 buildings remain on the city inventory. A patchwork of compliance timelines means the riskiest structures may be the last to be retrofit.
Attorneys who have handled seismic claims for two decades share what separates a credible expert from a liability to the case.
A field guide to the visual signatures that distinguish settlement, shrinkage, and active seismic movement in residential concrete.
In the weeks following the 1994 Northridge earthquake, a quiet consensus formed among structural engineers across Los Angeles: the building stock had failed in ways nobody had adequately anticipated. The damage was not evenly distributed. Certain construction types performed far worse than others, and the pattern of failures demanded a response.
What emerged over the following decade was a patchwork of municipal retrofit ordinances, each with its own timeline, its own definition of compliance, and its own political history. Thirty years later, the question worth asking is whether those ordinances achieved what they set out to do \u2014 and where the engineering profession still has work to do.
