In case It Is desired to Increnso the height of existing par ty or Independent walls, which walls are less In thickness than required under this title, It can be done by either using a lining of brick work on the Inside of walls, or building on top with Iron or steel construction, as may be approved by the Inspector of Buildings; provided, however, that the extra weight of Increased walls be supported entirely on Iron or steel construction carried down to walls of thickness required by ordinances, and the weight distributed on the walls to conform to sections 102 nnd 103 of this ordinance; provided, however, that no wall Is less than 12 Inches thick. Said steel work to be so de signed ns to give snfllclent stiffness to walls not of the required thickness, and to be fire-proofed In accordance with section 105. If brick lining Is used, the same shall form a combined thickness with the old wall of not less than four Inches more than the thick ness required for the new wall, corre sponding with the total weight of the wall when so Increased In height. The said lining shall be supported on proper foundations and carried up to such height as the Inspector of Hnlld lngs may require, No lining shall be less than eight Inches In thickness, ond oil lining shall be laid up in Port land cement mortar nnd thoroughly anchored to the obi brick walls with suitable wrought Iron anchors, placed not over two feet apart nnd properly fastened Into the old walls In rows alternating vertically nnd horizontally with each other, the old walls being first cleaned of plaster or other coat ings where any lining Is to be bull! against the same. Sec. 88. Add to end of section the following: "All bearing partition studs to be bridged through the cen ter of height of each story with suit able blocking of wood," so that, said section ns amended shall rend ns fol lows: Sec. 88.

Klght Inch brick and six-Inch and four-Inch hollow tile partition walls of hard burnt clay or porous terra cotta mny be built, not exceeding In their verti cal portion a measurement of fifty, thirty-six and twenty-four feet, re spectively, nnd In their horizontal measurement a length not exceeding seventy-five feet, unless strengthened by proper cross wnlls, piers or but tresses bonded Into same. All such walls shall be carried on proper foun dations or on iron girders, or on Iron girders and columns or piers of ma sonry. Dim line of fore and aft par titions in the cellar or lowest story, supporting stud partitions above, In ail buildings over eighteen feet be tween bearing walls In the cellar or lowest story, hereafter erected, shall be constructed of brick not less than eight Inches thick, or piers of hrick with openings arched over below the underside of the first tier of beams, or plera of brick, or 'Iron columns, with wooden girders when the first tier of floor benms are nf wood, or iron or steel girders when the Moor beams are of Iron or steel, or rolled Iron or steel beams of sufficient strength to span the entire width for the first tier of beams may be used, and tho stairs shall be Inclosed by a suitable brick wall carried up to the top of tho tier of beams nearest the curb line. Fore and aft stud partitions und such other main stud partitions as may be required by the Inspector of Buildings, which mny be placed In the cellar or lowest story of any building, shall have good solid stono or brick foundation walls under the same, which shall be built up to the top of the floor beams or sleepers, and the sills of said partitions shall be of yellow pine or other suitable hard wood; but If the walls flre built live Inches higher of brick than top of the floor beams or sleepers, any wooden sill may be used on which the studs shall be set. Fore and aft stud par titions that rest directly over each other shall run through the wooden floor beams and rest on the plate of the partition below. All girders sup porting the first tier of wooden beams in buildings shall be supported by brick piers, or Iron, locust or other suitable hard wood posts of snfllclent strength on proper foundations. "All healing partition studs to be bridged through the center of height of each story with suitable blocking of wood." Sec. 102. The last three lines to section to read "eleven nnd one-half tons per superileial foot, when good lime and Portland cement mortar mixed Is used, and fifteen tons per superficial foot when good Portland cement motuu' la used," so that said section as amended shall read hh fol lows; Sec. 102. Weight, of Ilullillng Ma terial. In computing the weight of walls, a cubic foot of brick work sluill be deemed to weigh one hundred mid fifteen pounds. Sandstone, white iiinrble, granite nnd other kinds of building stone shall be deemed to weigh iiim hundred and sl.Uy pounds per cubic foot. The sn I'e-beaiing load to apply to good brick work shall bo taken tit eight tons per superileial foot, when good lime mortar is used; eleven nnd one-half tons per super ileial foot, when good lime and Port land cement mortar mixed Is used; and fifteen tons per superileial foot, when good Portland cement mortar Is used. See. 103, The last paragraph to read as follows Instead of as In thu present ordinance: "Tho safe-bearing load to he applied to concrete, as de scribed In section 65, Is to be taken flt llfl.ccn tons per siiuire foot," so that section as amended sluill read as follows: See. 103. Safe-Heaving Loads for Knrth and Concrete. ilood, solid, natural earth shall be deemed to safely sustain a load of four tons to the superileial foot, or ns otherwise determined by the Inspector of llullii lngs, and the wldlh of the footing courses shall be at least sulllelent to meet this requirement.

Insert the word "medium" before the word "steel" In the fourth line. Insert the word "wrought" before the word "iron" In the fifth Hue. In like manner wherever the word "steel" Is used In this section It will he modified by the word "medium," and wherever the word "Iron" Is used In this section It will be modilled by the word "wrought." Wherever the word "steel" is used for rivets it shall ho modilled by the word "rivet." The ninth line, second and third words, shall read "or flange" Instead of "on flanges." The remainder of section to bo as at present. Amend section 107 so thnt said sec tion as amended shall rend as fol lows: Sec. 107. Maximum Stresses In Riveted Piute Orders. The maximum stresses In riveted plnte girders shall not exceed tho following, namely: Stresses In top and bottom Manges 1 4,000 pounds per square Inch for medium steel, and 1 2,000 pounds per square Inch for wrought Iron, net. area In each case; shearing stress In web 10,000 pounds per square Inch for medium steel, and 6,000 pounds per square Inch for wrought Iron; but no vveh plate shall be less than three eighths of an Inch In thickness. Hlv eted plate girders shall be proportion ed upon the supposition that the bond ing on flange strains are resisted en tirely by the upper and lower flanges, and that the shearing strains are re sisted entirely by the vveh plnte.
