What is the difference between crushing and buckling
Let me introduce with basic of columns Reinforced concrete column is a compression member and transfers the loads from structure to the ground through foundations. There are three types of concrete columns based on its height and lateral dimension

of the cylinder's length, fractures through either end. • Long Shear (dl): Diagonal fracture with no cracking through either end. • Columnar (e): Vertical cracking through both ends, no wellformed cones. • Crumbling (f): Typical of lowstrength concrete. Similar to type a, but with no wellformed cones.

MODELING THE BONDSLIP BEHAVIOR OF CONFINED LARGE
For low confinement conditions, splitting cracks can propagate radially through the concrete cover and the bond fails abruptly, as shown in Figure 3. When the con gages attached to two opposite sides of the bar near each end of the concrete cylinder and bar slips were measured at both ends by two linear potentiometers at each end

thin composite sheets were then employed to wrap 101.6 mm by 203.2 mm (4 inch by 8 inch) concrete cylinders. The bond length of the CFRC samples is 76.2 mm (3 inches) and 50.8 mm (2 inches) for the CFRP. A 38.1 mm (1.5 inches) gap exists between the top of the cylinder and the top of the composite sheets at both ends (see Figure 1). (a) (b)

When to worry about cracks in walls Building
When to worry about cracks in walls Narrow vertical cracks are most often caused by minor settlement or normal shrinkage. Such cracks are not structural defects. Wide vertical cracks (exceeding 3mm in width) may be caused by significant settlement problems that require detailed engineering inspection and evaluation.
