Notes‚ 1.The above table shows the short term allowable pull out load for
resin anchor bolts when embedded in for the length shown in the above table and in a drilled hole of the diameter shown above.
2.The concrete design characteristic strength is taken to be
Fc=17.6N/mm
2
.
3.When the dimensions differ from the above diagram, or if the
concrete design characteristic strength differs, then the pull out load may be calculated in accordance with the formulae for bolts on a strong foundation, on the left. However, the allowable pull out strength of one bolt may not exceed 11,760N.
4.It is desirable that ‚L 6d. The parts indicated by "-" in the above
table are not desirable.
5.If type 1 or type 2 lightweight concrete is used, allow 10% margin.
The short term allowable pull out load of a bolt is obtained from the following formula. However, if the shear stress in the bolt exceeds 44.1N/mm
2
(for SS400), bolt strength verification must be carried out,
and verification that the allowable tensile stresses are not exceeded must also be carried out. Here, Ta: Foundation bolt short term allowable pull out load (N) L: Foundation bolt embedded length (mm) d2: Concrete drilled hole diameter (mm) Fc: Concrete design characteristic strength (N/mm
2
)
For foundation bolts positioned in the corner or near the edge of the foundation, the short term allowable pull out strength shall be taken to be the minimum of the values from the formulae (a) above, or formulae (b) or (c) below. 1) for L C+h 2) for L>C+h Here, C : Distance from the center of the foundation bolt to the edge of the foundation (mm) However, C 4d or‚ p: Correction factor for concrete design characteristic strength Notes 1. It is desirable that L 6d (d=nominal diameter of foundation bolt) 2. If the concrete design characteristic strength Fc exceeds
29.4N/mm
2
, perform the calculation using 29.4N/mm
2
.
3. The diameter of the concrete drilled hole d2 shall be the the value
recommended by resin foundation bolt manufacturers.
4. If type 1 or type 2 lightweight concrete is used, allow 10% margin.
Installation location: a) Solid foundations
b) Upper surface of normal floor slab
c) Bottom surface of normal ceiling slab

Notes‚ 1.The above table shows the short term allowable pull out load for
resin anchor bolts when embedded in for the length shown in the above table and in a drilled hole of the diameter shown above.
2.The concrete design characteristic strength is taken to be

2
.
3.When the dimensions differ from the above diagram, or if the
concrete design characteristic strength differs, then the pull out load may be calculated in accordance with the formulae for bolts on a strong foundation, on the left, and divide the result by 1.5 to obtain the allowable pull out load. However, for foundation bolts provided in the bottom surface of ceiling slabs and on the surface of the concrete walls, the allowable pull out load may not exceed 7,840N per bolt.
4.It is desirable that ‚L 6d. The parts indicated by "-" in the above
table are not desirable.
5.It is necessary to investigate the short term pull out strength of
normal supports due to an earthquake provided in the bottom surface of ceiling slabs and on concrete walls for supporting heavy objects. For this short term pull out load, see Item b) short term pull out loads
6.If type 1 or type 2 lightweight concrete is used, allow 10% margin.
