Structural engineer John V. “Jack” Christiansen, a leader in the design of thin-shell concrete structures, died on Aug. 16 on Bainbridge Island, Wash. He would have turned 90 on Sept. 28. The most ...

A prototype for an ultra-thin, sinuous concrete roof using innovative design and fabrication methods has been designed and built by researchers from the ETH Zürich. The shell is part of a roof-top ...

Throughout the 20th century, a number of innovators experimented with fabric as a flexible membrane for the support of fluid concrete, forming structural members. Significant among the early ...

Thin shell structures are widely used in high-performance engineering due to their favorable strength-to-weight characteristics and capacity for distributed load-bearing. However, traditional ...
