Some Aspects of Structural Steelwork Design
To the general designer the task of designing large static structures seems simple; the functional requirement is merely that the object shall not fall down and shall not deflect excessively under load. The difficulties are these: firstly there is no chance of a prototype, the test bed is usually the general public; the second problem is that of economy. In a large structure most of the material has the job of supporting the other material. Even in railway trains and aircraft the dead-weight can greatly exceed the pay-load. In buildings and bridges any weight saved high up or at mid-span leads to extensive further savings.
