Nucor Skyline produces the beams used in beam and lagging excavation systems, most often either H-piles or wide flange beams. These beams are drilled or driven into the ground at regular intervals, then wood lagging beams for temporary walls or precast concrete slabs for permanent walls are installed between the flanges of the steel beams.

• For a continuous beam connected on both sides of the column web, see Figure 6.5a, the connection can be considered as a 'beam splice' with longer bolts. • If the beam is connected to a stiffened column web, see Figure 6.5b, the stiffeners between the column flanges create a similar effect as a connection to the column flange.

Precast concrete elements should be designed and constructed in compliance with the Building (Construction) Regulations and other relevant codes of practice. The design method specified in this code of practice for the design of precast concrete elements is the Limit State Design method. Alternative design approaches may be used provided that ...

beam, and the ends of the sup-porting cantilevers are similar to the ends of the dapped-end beams, but inverted. The use of dapped-end beams facilitates the erection of a precast concrete structure, due to the greater lateral stability of an iso-lated dapped-end beam than that of an isolated beam …

Precast columns may have corbels or nibs for supporting the beams. Alternatively, precast beam-column connections can be made using dowels or mechanical couplers. Precast concrete columns have the following advantages over in-situ concrete construction; Increased speed in construction since production of precast elements can commence ahead of time

The Stone Strong abutments can accept steel, timber or other Bridge Beam types. *On Short Spans you can design direct span (longitudinal) concrete slab beams without pre-stressing, practically to about 27' in length. *For Longer Spans you need a different type of superstructure. For the purposes of this presentation we will focus on steel beams or girders with precast transverse slabs.
