• Concrete Creep, Shrinkage Factors and Tensile Strength Calculation

Description:

This spreadsheet calculator provides values of creep factors, concrete tensile strengths and free shrinkage strains for use with finite element slab design programs that take account of concrete cracking (non-linear analysis). The methods used are those recommended in Concrete Society Technical Report No TR58.

With programs that do not account for cracking, substantially HIGHER creep factors should be employed, to allow for the increased displacements caused by cracking and shrinkage.

Quasi-permanent deflections (#1) should normally be within span/250.

Deflections affecting brittle partitions or cladding are the difference between those for frequent loading (#2) and those at the erection of the partitions or cladding (#3), and should normally be within span/500.
