The F-shape is generally similar to the Jersey barrier in appearance, but is taller, with somewhat different angles. [8] The UK equivalent is the concrete step barrier. [citation needed] First tested in 1968 by the then Department of Highways in Ontario, Canada, the Ontario Tall Wall is a variant of the Jersey barrier. [10]
The F-shape barrier is a concrete crash barrier, originally designed to divide lanes of traffic on a highway. It is a modification of the widely used Jersey barrier design, and is generally considered safer. [1] A parametric study, one that systematically varies the parameters, was done through computer simulations of barrier profiles labeled A ...
Products include: box culverts, 3-sided culverts, bridge systems, railroad crossings, railroad ties, sound walls/barriers, Jersey barriers, tunnel segments, concrete barriers, TVCBs, central reservation barriers, bollards, and other transportation products. Precast concrete can also be used to make underpasses, surface crossings, and pedestrian ...
Upright cabinets. Upright cabinets are the most common in North America, with their design heavily influenced by Computer Space and Pong.While the futuristic look of Computer Space 's outer fiberglass cabinet did not carry forward, both games did establish separating parts of the arcade machine for the cathode-ray tube (CRT) display, the game controllers, and the computer logic areas.
Barrier transfer machines can typically move their barrier segments anywhere between 4 and 24 feet (1.2 and 7.3 m) in one pass, usually at a speed between 5 and 10 miles per hour (8.0 and 16.1 km/h). Some models of the machine hold 50 feet (15 m) of barrier at a time as they are engaged in transferring.
Wii Vitality Sensor – A cancelled accessory for the Wii. Announced by Satoru Iwata at E3 in 2009, [1] not much is known about the Vitality Sensor and how it would have been integrated into video games. It has been suggested by Iwata that it would be used to relax the player, telling them their heartbeat and about their body.
The Filigree Wideslab method is a process for construction of concrete floor decks from two interconnected concrete placements, one precast in a factory, and the other done in the field. The method was developed during the late 1960s by Harry H. Wise as a more efficient and economic construction process than conventional cast-in-place technologies.
Logo of Eurocode 2 An example of a concrete structure. In the Eurocode series of European standards (EN) related to construction, Eurocode 2: Design of concrete structures (abbreviated EN 1992 or, informally, EC 2) specifies technical rules for the design of concrete, reinforced concrete and prestressed concrete structures, using the limit state design philosophy.
