Beam & Column Links Options

4 Link Legs as 2 Equal links:

Normally 4 link legs will detail as 1 large and 1 small link. This gives a stable cage with low risk of loosing the side cover. However this is not always desirable as the internal link can be narrow and requires 2 separate links to be detailed.

This option allows you to use 2 equal size links of 2/3 width. Caution must be exercised when using this option as the links could spread during concrete pouring and thus reduce the side cover.

Open Links with closer:

Detail the links as open links (77 and 55) with a 35 closer.

As a Slab (no links):

Omit links from beam, and detail as a slab.

See section below on Real Slabs.

Internal Link Equal width :

Normally 6 link legs will detail as1 large, 1 medium and 1 small link. This option will give you 1 large and 2 small links.

Single leg internal links

All internal links to be single leg links shape 85.

Replace Shape code 85 links with U-Bars

Replace Shape code 85 links with short horizontal 38 U-Bars for easier placement on site. Internal links will not be replaced unless they are 85’s.

This function is best used if Open Links with closer and Single leg internal links are active
