Is there commercially available strain gage monitoring system such that you can see in the monitor the strain conditions of shear, flexural, moment, axial load of beams and columns by strain gage being distributed in key positions of the concrete elements with wires running to a central computer...
How many years or decades before a beam can creep significantly and big is the strain difference between original and decades later (let's say for a typical beam of 500mm) depth?
How would the rebar react to the creeping concrete. Would it debond or would rebar creep too along with the concrete?
When you do coring tests on concrete like columns. What is the best replacement materials for the 50mmx100mm holes? Concrete is 4000 psi. What compressive strength results do you consider failure after concrete is 3 month old?
Has anyone designed a one way 4" slab with dimensions 3 meter by 6 meter that is fully anchored in the long span 6 meter side (to beams) but one of the short span 3 meter side open? One way slab means the long span side is attached to the beam by top bars and continuous lower bars.
See attached layout. In the 3 middle columns portion, what part of the beams would have the maximum moment and shear? The secondary beams attached to the girders can be said to be point loads?
