Reinforcing Steel.
4.
Symptom:  Small cracks may be evidence that stirrups and tensile steel may be
inadequate.
Remedy:  Perform a load test on an outlooker and measure deflections. If load
test demonstrates inadequacy of the outlooker, increase the strength by
appropriate methods.
Based on the test results, it was determined that the outlooker was
adequate to carry the design load.  It is noted that the outlooker-handrail
system is anchored without any allowance for expansion and contraction.  It is
predicted that during periods of large temperature differentials, expansion
cracks will appear.  For this reason, it is strongly recommended that a
monitoring system be instituted which will report unusual movements and
subsequent cracks.
