SCI P287: Design of Composite Beams using Precast Concrete Slabs

This publication provides guidance on the design of steel beams acting compositely with precast concrete slabs in multi-storey buildings. The use of hollow core or solid plank precast units offer benefits in terms of cost (the long spanning capabilities of the precast slabs lead to fewer secondary beams) as well as the advantages offered by composite construction. The design basis is generally in accordance with BS 5950-3, supplemented by recommendations from Eurocode 4 and data from tests. Particular issues affecting the use of precast concrete concern the requirements of effective shear connection and transverse reinforcement. Small-scale push-out tests, and earlier composite beam tests, have established reduction factors for the design resistance of welded shear connectors as a function of the gap between the ends of the precast concrete units, and the amount of transverse reinforcement provided.
The guidance also emphasises the importance of the design of the steel beam in the non-composite construction stage, where out-of-balance loads can occur during installation of the precast concrete units. The guidance applies to hollow core units of 150 to 260 mm depth, and to solid precast planks. A step-by-step design procedure is given for composite beams using various forms of precast concrete units, with or without a concrete topping. This is supplemented by a fully worked design example for a composite beam in a 15.8 m × 7.2 m grid, and a series of design tables for concept design.

ISO 22965-2 Concrete — Part 2: Specification of constituent materials, production of concrete and compliance of concrete

This part of ISO 22965 applies to concrete for structures cast in situ, pre-cast structures and structural pre-cast products for buildings and civil engineering structures. The concrete can be mixed on site, ready-mixed concrete or produced in a plant for pre-cast concrete products.
This part of ISO 22965 applies to concrete compacted to retain no appreciable amount of entrapped air other than entrained air and to normal-weight, heavy-weight and light-weight concrete. Other International Standards for specific products, e.g. pre-cast products, or for processes within the field of the scope of this standard can require or permit deviations from this part of ISO 22965. This part of ISO 22965 specifies the properties of constituent materials, the production of concrete and the compliance system of concrete.
This part of ISO 22965 does not apply to:
⎯ concrete with a maximum aggregate size equal to or less than 4 mm or 5 mm (mortar),
⎯ aerated concrete,
⎯ foamed concrete,
⎯ concrete with an open structure (“no-fine aggregate” concrete),
⎯ concrete with a density less than 800 kg/m3,
⎯ refractory concrete.
This part of ISO 22965 does not cover health and safety requirements for the protection of workers during production and delivery of concrete.

SCI P180: Integral Steel Bridges - Design of a Single-span Bridge - Worked Example

This publication provides a Worked Example for the design of a single-span fully integral bridge, that utilises High Modulus Pile abutments and a composite plate girder deck. It has been based on the findings of studies undertaken on steel integral bridges and steel substructures by The Steel Construction Institute since 1993.
Calculations are provided for each design stage, together with a detailed commentary explaining the background to the methods employed and the parameters chosen. Computer-based numerical techniques have been used to enable full soil-structure interaction to be considered in the analysis. A design is proposed for a reinforced concrete capping beam to provide a full moment connection between the High Modulus Piles and the deck.
