Constant-stress arches - Q&A with Wanda Lewis

After 30 years studying the shape of tension fabric structures and observing principles of constant stress expressed in natural objects, Professor Wanda Lewis decided to apply the concept to bridge structures. She believes that the outcome – a method for designing arch bridges with a constant stress – could bring a number of benefits. Lewis talks to Jose Sanchez de Muniain.
