Structural loads
As everyone might know that great architecture is the successful marriage of art and technology – and a structure is an artifact expressing one of the many aspects of human creativity, however it is an artifact that cannot be created without a deep respect for the laws of nature. And that is the main problem brought out by the author of the book „Why buildings stand up“, Mario Salvadori.
So why should an engineer consider different loads? the answer is simple - if the earth did not pull , the wind did not blow, the earth's surface did not shake or sink and the air temperature did not change , then loads would not exist and structure would be unnecessary. This would be so-called the Alice -in-Wonderland world of architecture. But in the real world the engineer's first job is to determine which loads will act on a structure and how strong they might be in extreme cases . This is anything but a simple task.
Loads are further divided into environmental loads, thermal, settlement and sesmic loads. Then there are live loads – these are the impermanent loads, that may be shifted around and change in value, for instance – people, furniture, equipment and other stored goods . In addition, there are dead loads, which are permanently there and support their own weight – these are the heavy elements like columns, beams, floors, arches, domes, but also ceiling and inslulation material. Finally , it leaves us with other loads – corrosion, fire and loads during construction .
First of all, thermal loads are sometimes called hidden or locked-in
