Calculation of metal four-jointed arched compliant support
Authors:
Abstract
A four-hinged brace is a statically defined geometrically variable system with one degree of freedom. In ground structures, geometrically variable systems are almost never used due to their instability. Therefore, the construction mechanics does not provide a specific methodology for their calculation.
