This method is a return to the essentials of building, and a key direction for building innovation.
With a close cooperation between architects and structure engineers, an accurate consumption of material and layout is possible according to the mechanic calculation.
The roof structure of International Terminal, Waterloo, designed by Nicholas Grimshaw Partners and Anthony Hunt Engineering Partners, is a typical model for form developed by employing structural force diagram.
In modern architecture, exposed structure is preferred to decoration, which requires the material shall reflect the structure and component property, which is a key idea of modern architecture aesthetics, profoundly influencing the application of building materials [4].
