abutment

The abutment towers are similar to the river towers.

159On the abutment towers the chains are connected by horizontal links, carried on rockers, to anchor ties.

116When arches form the superstructure, the abutment must be so designed as to transmit the resultant thrust to the foundation in a safe direction, and so distributed that no part may be unduly compressed.

86That at the left abutment is R 1 =W 1+ W 2+ ...-R2.

79Each chain over a shore span consists of two segments, the longer attached to the tie at the top of the river tower, the shorter to the link at the top of the abutment tower, and the two jointed together at the lowest point.

52The reaction at the right abutment is R4 = W1x1/l+W2x2/lrt ..

44The methods of erection may be classed as - (I) erection on staging or falsework; (2) floating to the site and raising; (3) rolling out from one abutment; (4) building out member by member, the completed part forming the stage from which additions are handled.

21From the abutment of the Hindu Kush on the Sarikol in the Pamir regions to Landi Kotal, and throughout its eastern and southern limits, the boundary of Afghanistan touches districts which were brought under British political control with the formation of the North-West Frontier Provinces of India in 1901.

21Wedged in between the railway and the Indus, but still north of the railway, is a curious mass of rough mountain country, which forms the southern abutment of the Suliman system.

21We can now Indianrs - fully appreciate the factor in practical politics which Afghan- that definite but somewhat irregular mountain system, represents which connects the water-divide north of istan Herat with the southern abutment of the Hindu Kush, near Bamian.

22In finding the abutment reactions some principle such as the principle of least action must be used, and some assumptions of doubtful validity made.

22Eads, the engineer, determined to establish the piers and abutments on rock at a depth for the east pier and east abutment of 136 ft.

22For suspension bridges the abutment forming the anchorage must be so designed as to be thoroughly stable under the greatest pull which the chains can exert.

22The principal measurements are: each abutment 176 ft.; from abutment to side tower, 230 ft.; from side tower to central tower, 460 ft.; breadth of each side tower at road-level, 32 ft.; breadth of centre tower, 45 ft.

22Once it chanced that I stood in the very abutment of a rainbow's arch, which filled the lower stratum of the atmosphere, tinging the grass and leaves around, and dazzling me as if I looked through colored crystal.

22above Trinity high-water mark; the arches on each side of the centre have a span of 140 ft., and the abutment arches 130 ft.

00For spans over 75 ft., expansion due to change of temperature is provided for by carrying one end of each chain girder on rollers placed between the bearing-plate on the girder and the bed-plate on the pier or abutment.

00- The fortress draw-bridge is the original type, in which a single leaf, or bascule, turns round a horizontal hinge at one abutment.

00A more common type is a bridge with two leaves or bascules, one hinged at each abutment.

00If it revolves about a vertical axis d its centre of gravity must always lie in that axis; if it rolls the centre of gravity must always lie over the e abutment.

00If the bridge is erected when the river is nearly dry a travelling stage may be constructed to carry the projecting end of the girder while it is hauled across, the other end resting on one abutment.

00Towards the northern extremity of the range occur a group of peaks, which together form an oblong block or " massif °' amongst the neighbouring ridges known as " Kaisargarh " amongst the Sherani clansmen who occupy it; and as the " Takht-i-Suliman " (Solomon's throne), generally, on the frontier, from the fact of a celebrated shrine of that name existing near its southern abutment.

00A car, an unrecognizable hulk of blackened metal, was ground against the concrete abutment of an over pass in a puddle of water.

00He paused, leaning against a concrete abutment, mesmerized by the never-ending torrent as it flowed over the edge of the dam.

00A popular tavern was pulled down at the location of the northern abutment.

00Another wooden pier, five sided, acts as a respond against the eastern abutment.

00The southern abutment was flanked by two retaining walls which held small triangular embankments against its sides, thus strengthening it laterally.

00A more common type is a bridge with two leaves or bascules, one hinged at each abutment.

00- The girders are longer than the span and the part overhanging the abutment is counter-weighted so that the centre of gravity is over the abutment when the bridge is rolled forward (fig.

00(b) The axis of rotation is on one abutment, and the bridge is then usually unequal armed(fig.

00(c) In some small bridges the shorter arm is vertical and the bridge turns on a kind of vertical crane post at the abutment (fig.
