concrete anchor pull out strength

Combined Concrete Cone Failure and Anchor Bolt Pullout Failure This failure mode can be a time consuming calculation for chemical anchor design as it depends partly on the anchor bolt pullout strength and partly on the concrete cone resistance The CivilWeb Concrete Anchorage Design Spreadsheet completes all the above calculations instantly and allows the designer to

Wedge anchors should be used only in solid concrete Length To determine the length of wedge anchor required add the thickness of the material to be fastened plus minimum embedment plus the thickness of the nut and washer The sum of these three items equals the minimum wedge anchor length The Wedge anchor requires no maximum hole depth The depth of the

anchor rods required by this provision becomes impractical and 2 there is an apparent Figure 1 – a Base connection with individual anchors b base connection with anchors connected to an embedded plate a b 4 dichotomy wherein the strength of a similar detail for reinforced concrete columns calculation with hooked reinforcement bars extending into the footing is not

STUDY ON DYNAMIC PULLOUT STRENGTH OF ANCHORS BASED ON FAILURE MODES Hiroshi SATO1 Kazunori FUJIKAKE 2 and Sidney MINDESS3 SUMMARY This study investigates the effect of loading rate on the ultimate pullout resistance of anchors set into concrete based on the failure modes Thus rapid pullout loading tests of cast in place

This calculator will determine the variables for a Concrete Anchor subjected to Tension Pullout Force per ACI 318 02 The American Concrete Institute ACI has adopted Building Code Requirements for Structural Concrete ACI 318 02 and ACI 318R 02 as a construction standard in 2001 For the design of members the Code also introduces new concepts of compression
