Building Systems Flashcards
Each pair of external columns supports long spanning beam or girders; suitable for long narrow building desired
One Way Beam System
Two layer system, beam frame into girder increase floor depths and more space for mechanical systems; contribute lateral stabilty
Two Way Beam System
Large column free space required, long spanning plate girder carry primary beam, turn support layer of secondary beam
Three Way Beam System
Top covering of the building; protection from weather, oldest components of buildings
Roof
Horizontal line of intersection between two sloping planes of a roof
Ridge
Inclined projecting angle adjacent sloping sides of a roof
Hip
Intersection of two inclined roof surafce toward rainwater flows
Valley
