Anchorage in Concrete Construction is a comprehensive treatment of current fastening technology including inserts, post-installed anchors, as well as power-actuated fasteners, in both concrete and masonry.

Features:

• Describes in detail these elements together with their behavior and load-bearing capacities in cracked and uncracked concrete, while also considering the effects of corrosion and fire, as well as earthquake and shock loading
• Demonstrates an assessment of fastenings, illustrated by numerous examples
• Details several different types of masonry and describes the load bearing characteristics with an assessment of plastic fastenings and injection-molded anchors, including criteria for selecting the correct fastening
