TYPES OF Mm* BUILDINGS 3 



3. Mill Buildings with Masonry Walls. Buildings of this 

 type are made by supporting the roof trusses directly on brick, stone 

 or concrete walls. The construction of the roof is essentially the same 

 as for types (i) and (2), except that the trusses are somewhat lighter 

 on account of the smaller wind stresses. 



The discussion of the simple steel frame mill building shown in 

 Fig. i includes practically all the problems and details which are en- 

 countered in the design of steel mill buildings of all types. 



The problems involved in the design of mill buildings will be di- 

 vided into Part I, Loads ; Part II, Stresses ; Part III, Design of Mill 

 Buildings; and Part IV, Miscellaneous Structures. In general the 

 discussion will relate to the design of mill buildings but in a few cases, 

 particularly in stresses, quite a number of problems will be discussed 

 that are only indirectly related to the subject.
