FIGURE 9.20 (a) Minimum lap splice length for deformed welded-wire fabric.<br />

(b) Slab reinforced with deformed welded-wire fabric.<br />

FIGURE 9.21 Minimum lap splice length for plain welded-wire fabric. Use the<br />

larger of the values shown in (a) <strong>and</strong> (b). In calculation of splice length, the computed<br />

value of development length L d, not the minimum required value, should be<br />

used. (a) Splice length when steel area used is less than twice the required area. (b)<br />

Splice length when steel area used is two or more times the required area. (c) Slab<br />

reinforced with plain welded-wire fabric providing twice the required reinforcement<br />

area.
