The end walls, fire wall and outside wall are of plain concrete, the 

 latter being enlarged by buttresses or pilasters between stall spaces 

 to carry the outer ends of the radial roof girders, which are further 

 supported by an outside wall column, and two intermediate columns. 

 The combined roof, wall and column construction is shown in Fig. 185. 

 Each radial girder consists of an 18" @ 55 Ibs. I-beam encased in 

 concrete as shown in Fig. 186, and is supported by an outside wall 

 pier and three I-beam columns enclosed in concrete as shown in Fig. 

 187. The space between the main roof girders is spanned by rein- 

 forced concrete beams, carrying a reinforced roof slab and a suspended
