The document discusses static analysis for building structures. It defines the different directions external loads can act and the importance of understanding how forces are transferred through components. It then describes 7 different building component functions - beam, slab, column, tie rod, shear, portal frame, and triangle constructions - and the characteristics of loads on each. The document concludes with discussing how to apply static analysis by checking components can fulfill functions, whether calculations are needed, and illustrating force distribution with sketches.
