Influencing Factors

Influence of Concrete Strength

 

Influence of Edge Distance*

* The above influencing factors must apply for every edge distance smaller than critical edge distance . Actual edge distance shall not be smaller than minimum edge distance

 

Influence of Anchor Spacing**

** The above influencing factors must apply for every anchor spacing smaller than critical spacing distance . Actual anchor spacing distance shall not be smaller than minimum spacing distance .

 

SHEAR – Concrete Capacity CC Design Method

Design shear resistance

 

Design Concrete Edge Resistance,

 

Design Concrete Pryout Resistance,

 

Design Steel Resistance,  

 

Influencing Factors

Influence of Concrete Strength

Influence of Edge Distance*

* The above influencing factors must apply for every edge distance smaller than critical edge distance . Actual edge distance shall not be smaller than minimum edge distance

Influence of Anchor Spacing**

** The above influencing factors must apply for every anchor spacing smaller than critical spacing distance . Actual anchor spacing distance shall not be smaller than minimum spacing distance .

 

Influence of Shear Loading Angle

 

Influence of anchoring spacing and edge distance for concrete edge resistance

Formula for single-anchor fastening influenced only by edge

 

For single anchor

 

Formula for two-anchor fastening valid for S<3c

 

General formula for n-anchor fastening (edge plus n-1 spacing) only valid where to are all < 3c and >1.5c

Note: It is assumed that only the row of anchors closed to the free concrete edge carries the centric shear load.

 

For 2 anchors
