Identification of Cracks

aim

to complete the challenges

1.a

a concrete is crushed and the steel are exposed

a crack develep bottom to top that means rebar yeilding occur bottom support

a fluxtural failure due to reverse stress

during reversal stress support top is compression and bottom is tension.

top compresion is managed by slab

reinforecemet got yielded and not to be repaired

b. a beam look like seperate from column

insufficient development length of joints

c. cracks develope column beam joints

it is a plastic hing failure

a damage occured in joints

cyclic lateral loading and the stress reversal at the joints led to the damage

the joint can be strengthened

2.a

a concrete damage top and face of column

its a soft story failure

absence of infill wall at ground floor the plastic hinge form top of column

b concrete is completely breakage

its a less shear reinforcement

insufficent shear reinforcement so concrete take a shear

c column failed completely and it also top

so its a short column and may be lower slab provided

in this failure is not repaire

results

challenges are completed
