In this paper, a novel steel-concrete bolted connector, consisting of a short bolt, a long bolt and a coupler, is proposed.
Some key parameters, such as the gap between steel plate and concrete panels, bolt spacing, width of steel strips, and steel panel slenderness, are investigated through numerical analyses.
The cross, made of metal tubing reinforced with concrete and bolted to a base on a rock, about 200 miles east of here, was discovered missing Monday.
The construction used of gunite, of concrete, 24,000 bolts, of water- and frost protection, of noise- and frost isolation and 9.4 km of cable conduit.
Rebuilding of large public buildings bears the lessons of Haiyan – new schools have grills on windows; reinforced concrete beams and bolts in the ceiling that allow the roof to judder a little in high winds without ripping away.
An extensive set of these measurements establishes a network of points both on the map, where their positions are plotted by their coordinates, and on the ground, where they are marked by pillars, concrete ground marks, bolts let into the pavement, or wooden pegs of varying degrees of cost and permanence, depending on the importance and accuracy of the framework and the maps to be based on it.
Sprayed concrete and rock bolts are the main support measures.
Launch site services are planned to be austere — primarily a concrete pad with bolt-down fixtures and generator or shore power".
It was found that although column-base plate strong-axis connections were properly designed in accordance with design guides, the flexural performance of the connections could be unreliable without sufficient bond capacity between concrete and anchor bolts.
The structural response of the beam-to-column joints is assessed under a monotonically increasing static load and the influence of the type of precast concrete slab and bolted shear connectors, as well as degree of shear connection, on the structural performance of this structural system are investigated.
