In this paper the writer has endeavored to find the most economical design that will satisfy all conditions under which the building is to be erected. The most economical structure is one that will give the best service for the smallest cost. Of course it is not desired to erect the cheapest structure because, when considered over a long period of years it often proves the most costly. Besides the cost the quality and life of the structure will be considered. There are several factors that have been considered in designing this structure. Some of these are: (1) Use to which the building is to be put; (2) The period of years over which the building is to be used; (3) The climatic conditions; and (4) The ease with which material may be obtained and erected. In solving a problem of this type there must be many assumptions. Many of the assumed values are found to be incorrect, and when this happens a new value must be assumed and the calculations repeated. The problem is therefore solved many different times, each time with a new assumed value. In this way the most satisfactory and economical result is obtained. The overall sizes of the structure depends largely upon the space allowed for it in the Architectural design. Quite often the structural design is made more difficult by architectural features which most not be altered. In this problem the Architectural design was made by Professor C.H. Cowgill. This design was worked under the supervision of Professor C.H. Cowgill. Head of the department of Architecture, Virginia Polytechnic Institute. / M.S.
