Cracks in Buildings – Elastic Deformation

Preetham Builders one of the Best Builders in Madurai are developing Gated Community Luxury villas and flats.

This gated community ” BRINDAVAN HOMES ” is being developed in Kochadai Madurai, a fast developing area in Madurai.

With abundant water supply and green environments this gated community ” BRINDAVAN HOMES ” with individual buildings and Bungalows present a Resort like feelings.

Preetham Granite M.D addressed the gathering of engineers (Association of Madurai Civil Engineers) on Cracks in Buildings – Causes & Remedies at Hotel Weshtern Park ( 01.09.2016).

 

Elastic deformation:

Structural members undergo elastic deformation due to load.

Brick masonry uneven loading

Deflection of large beam / slab

Unequal stress: central wall subjected to over loading

Portion A heavily loaded than portion B

 

Brickwork over RCC beam to be done after the beam attains deflection due to self weight.

Construction of brick masonry with pillar

Remedies

Grooving

Wiremesh lath

 

Horizontal Cracks in Brick Panels of a Framed Structure

 

Vertical Crack in Brick Panel Wall of Framed Structure Due to Expansion of Brickwork

 

When Length to Height Ratio of Partition is Large and there is no Door Opening.

 

When Length to Height Ratio of Partition is Small and there is no Opening

 

When Length to Height Ratio is Large and there is Central Door Opening

Cracking in a Partition Wall Supported on RCC Slab/ Beam, When Length to Height Ratio is Large and there is a Central- Door Opening:

In this case diagonal cracks occur because of combined action of flexural tension in the porton of masonry above the opening and self weight of unsupported masonry on the sides of the opening. Cracks start from lintels where thery are widest and get thinner as they travel upward.
