⇒What are defect of high rise buildings.

A structural defect is defined as actual physical damage to the designated load-bearing elements of a structure, or the ingress of water into the waterproofing envelope, attributable to a defect in design, workmanship or materials, to the extent that the structure becomes unsafe or otherwise unlivable.

Defect:- A defect is a building flaw or design mistake that reduces the value of the building, and causes a dangerous condition. A construction defect can arise due to many factors, such as poor workmanship or the use of inferior materials. Building defects do not appear to have been minimized despite recent advancements in building technology. Some common defects caused by agents such as atmospheric pollution, poor workmanship or the use of inferior materials and climatic conditions are more frequent. Defective building construction not only contributes to the final cost of the product but also to the cost of maintenance, which can be substantial. Defective construction includes activities such as compaction not done to specifications leading to ground subsidence and eventual early deterioration of foundations. This may lead to the complete failure of a structure. Conditions under which building construction takes place are often far from ideal with the focus mainly being on speedy delivery. Defects resulting of inaccurate construction can be avoided by ensuring that proper inspection mechanisms are in place. The understanding of building defects and their causes is essential for better performance of any building. Broadly speaking, building defects fall into two categories viz. defects that affect the performance of structure and defects that affect the appearance of structure.

Construction defect of high rise buildings.

→ A construction defect is generally defined as a defect in the design, the workmanship, and/or in the materials or systems used on a project that results in a failure of a component part of a building or structure and causes damage to person or property, usually resulting in financial harm to the owner.

                                           

What are the causes of building defects?

→ Improper or poor quality of the materials. Defective material or poor material performance. Missing or inadequate protection from weather or environmental condition in the construction site. Soil subsidence, movement and settlement.

Weakest part of Building.

→With the pillars on the edges, the V-shaped load distributors, and the light mass of the building, the corners are the weakest part of the building.

→How many floor is considered a hihg rise building

a high-rise as "A multi-story structure between 35–100 meters tall, or a building of unknown height from 12–39 floors."

Common types of Building Defects ↴

• Non-structural cracks. Hair-line cracks. ...
• Spalling of concrete. Stains of water or rust are found on the surface or there is seepage of water. ...
• Structural cracks. Cracks that penetrate the surface rendering into the structural concrete or load-bearing brick wall. ...
• Defective external wall finishes.
• Damaged roofing and blocked guttering. Cracked roof tiles or damaged 'pointing' (the cement sealant along the roof joins) can leave your roof and ceilings exposed to water damage and flooding. ...
