Plated structures subject to out of plane loading. Hybrid construction, using materials of different yield stress is not included. Total load for ultimate limit state: BS is a British Standard code of practice for the design and construction of steelconcrete and composite bridges.
Loading per beam at 3. The concrete deck and live loading are included to demonstrate the use of load factors only, they do not represent a solution for a deck design.

Deformed bars, 2. The effective perimeter of a single bar may be taken as 3. The effective perimeter of a group of bars see 5. A link may be considered to be fully anchored if it passes round another bar of at least its own size through an angle of 90p and continues beyond for a minimum length of eight times its own size, or through p and continues for a minimum length of four times its own size. In no case should the radius of any bend in the link be less than twice the radius of the test bend guaranteed by the manufacturer of the bar. Continuity of reinforcement may be achieved by a connection using any of the following jointing methods: a lapping bars; b butt welding see 4. Such connections should occur, if possible, away from points of high stress and should be staggered appropriately.

Cracks in concrete can be caused by: corrosion of the reinforcement which causes the concrete to spall thermal movements, particularly cooling from heat of hydration called early thermal cracking structural actions such as bending, shear or torsion Corrosion of reinforcement is controlled by use of suitable concrete grades and providing adequate cover to the reinforcement. Cracks due to thermal movements are controlled by providing minimum nominal steel area and restricting the maximum bar spacing. The width of shear cracks is controlled by ultimate strength calculations. Only the crack widths caused by bending and tension need to be calculated and clause 5. For calculating the crack width only combination 1 loading is used and a maximum of 30 units of HB is applied. Cracks caused by higher loadings will not exist for long enough to affect corrosion. The maximum design stress limits will ensure that the cracks close up when the loads are removed.
