Page 757 - D — A building with masonry walls, but otherwise ordinary or joist construction and wood finish. Type E — A frame building constructed with wood above foundation, with or without slate or other semi-fireproof material on roof.
Page 330 - Every floor shall be of sufficient strength to bear safely the weight to be imposed thereon in addition to the weight of the materials of which the floor is composed...
Page 8 - The perpendicular distance between the lines of action of the two forces is called the arm, and the product of one of the forces and the arm is called the moment of the couple.
Page 567 - Rd (16) where d is the perpendicular distance from R to the center of gravity of the section under consideration. This moment can also be expressed in other terms. If e of Fig.
Page 141 - T-beams shall not exceed one-fourth of the span length of the beam, and its overhanging width on either side of the web shall not exceed eight times the thickness of the slab nor one-half the clear distance to the next beam.
Page 95 - These are in one class of equal length, and in another class of unequal length. Notice also the fillet and curve at outer edge. The method of increasing the weight is shown by the full lines. It will be seen, therefore, that for an angle with certain size of legs the effect of increasing weight is to change slightly the length of legs, and to increase the thickness. In case of angles, the distinction between "standard...
Page 465 - ... the leeward side of a shop building, or monitors at the ridge, will relieve all or a part of the pressure due to suction. This action should be recognized and provided for to the extent of making all members capable of resisting a reversal of stress, and by providing proper anchorage of trusses. 16. Snow Loads. — The snow load to be carried by a roof truss is a variable quantity, depending upon the slope of the roof, the latitude, and the humidity. Dry freshly fallen snow weighs about 8 Ib....
Page 338 - ... thin edge in the projecting flange or arms of the cross sections does not exceed three-quarters of an inch in thickness. The thickness of the fireproof covering on all surfaces measuring more than three-quarters of an inch wide and measuring in a direction perpendicular to such surfaces shall be not less than that specified for interior columns in the beginning of this section, and all spaces, including channels or chases between the fireproof covering and the metal of the columns, shall be filled...
Page 330 - ... or other masonry arches or with concrete or reinforced concrete slabs; wood may be used only for under and upper floors, windows and door frames, sashes, doors, interior finish, hand rails for stairs, necessary sleepers bedded in the cement, and for isolated furrings bedded in mortar. There shall be no air space between the top of any floor arches and the floor boarding.
Page 331 - Every plank, slab and arch, and every floor beam carrying one hundred square feet of floor or less, shall be of sufficient strength to bear safely the combined dead and live load supported by it, but the floor live loads may be reduced for other parts of the structure as follows: — In all buildings except armories, garages, gymnasiums, storage buildings, wholesale stores, and assembly halls, for all flat slabs of over one hundred square feet area, reinforced in two or more directions and for all...
