This exception allows for the standard 5-axle semi-truck configuration to gross up to 80,000 pounds (36,000 kg) (the legal limit) [9] without being in violation of the bridge formula law. Without it, the bridge formula would allow an actual weight of only 66,000 pounds (30,000 kg) to 67,500 pounds (30,600 kg) on tandems spaced 36 feet (11 m) to ...
The ST-26 was intended to provide for crossing of trenches and streams 6–6.5 m (20–21 ft) wide and barriers up to 2 m (6.6 ft) high by T-27, T-26 and BT light tanks: the bridge had a maximum load rating of 14 tonnes (15 short tons). The bridge could be laid with the help of the cable winch in 25–40 seconds without crew exit; the raising ...
The arches are semicircular, and their thickness T depends both on the span a of the arches and on the height H of the structure: [7] If H = 2.5 a, T = 0.1 a + 0.04H If H < 2.5 a, T = 0.125 a + 0.04H However, if the span a is small (a<8 m), it is preferable to use the following formula for T: T = 0.15 a + 0.4.

Factory No. 174 produced engines and spare parts for the T-26, installed additional armour plates on some T-26s, replaced flame-throwers with 45 mm tank guns in turrets of 130 KhT-133 flame-throwing tanks, repaired tanks in army units (846 T-26s since the beginning of 1941) and mounted about 75 turrets from the T-26 and the T-50 as bunkers for ...

The posted weight limit of the bridge was 26 short tons (24 t) [16] and it carried more than 14,000 vehicles per day, [17] with a posted speed limit of 35 mph (56 km/h). [14] The bridge was inspected most recently on September 19, 2021, [18] and the last inspection report was released in May 2022. [19] Bridge pier in 2015.
Unlike an I-beam, a T-beam lacks a bottom flange, which carries savings in terms of materials, but at the loss of resistance to tensile forces. [5] T- beam designs come in many sizes, lengths and widths to suit where they are to be used (eg highway bridge, underground parking garage) and how they have to resist the tension, compression and shear stresses associated with beam bending in their ...
ASHEVILLE — Two concrete segments jutting out over Interstate 26 will soon be 3 feet apart — and connected later this spring — into a new Blue Ridge Parkway bridge, according to a Feb. 14 ...
