What are defect of high rise buildings.causes of building defects?


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.

→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. ...

Design of Structures: Welded Connection

Image
INTRODUCTION The development of welding technology in 1940s has considerably reduced the riveted joint applications. Welding is the method of locally melting the metals (sheets or plates – overlapping or butting) with intensive heating along with a filler metal or without it and allowing cooling them to form a coherent mass, thus creating a joint. A typical weld showing various zones of weld is shown in Fig. 7.1. Such joints can be created to make structures, boilers, pressure vessels, etc. and are more conveniently made in steel. The progress has been made in welding several types of steels, but large structure size may impede the use of automatic techniques and heat treatment which becomes necessary in some cases. Welded ships were made in large size and large number during Second World War and failures of many of them spurted research efforts to make welding a better technology. ADVANTAGES OF WELDED CONNECTIONS The gross sectional area of the welded members is effective since the we

failure of a rivet joints

Rivet Rivets are short ductile and cylindrical bars that are used for making a permanent mechanical joint. The process of forming a riveted joint is called riveting. A rivet is divided into 3 parts i.e., the head at one end, the tapered tail, and shank, The portion between the head and tail as shown in the figure. As it is a permanent joint it cannot be disassembled without the failure of the machine component. The material of rivet should be tough and ductile. They are usually made of low carbon steel, nickel steel, Brass, Aluminum, copper, etc. Physics Behind Rivetting. The main function of a rivet is to make a connection, That has the strength to prevent failure and tightness to prevent leakage. For connecting “> 2 metal plates, firstly holes are punched and reamed. The plates are then separated to remove any burrs or chips. The cylindrical cold or red-hot rivet is then inserted into the hole. Then the head is backed by a hammer or heavy bar and then the Die as shown in the figur

What is Rivet Value? and Efficiency of a rivet joint:-

Image
What is Rivet Value? It is defined as the maximum safe force one rivet can withstand. The strength of a rivet in shearing and bearing is calculated and the lesser value is taken as Rivet value. Beyond this value, the rivet will either fail in shear or will be crushed in bearing. the value of shearing and bearing strength one rivet can be calculated from the following relations:- Note :- Rivet value is least of the equations (i) and (ii) Efficiency of a rivet joint:- The original strength of a structural sheet section is reduced by rivet holes provided in it. The efficiency of a rivet joint is the ratio of the strength of riveted joint to the strength of the solid plate(Ex. strength of solid plate without rivet hole). It is denoted by  ɳ  and is expressed as percentage. The effectiveness of a particular riveted joint is measured by the efficiency. Mathematically efficiency is expressed as:                                                                            ɳ  = Strength of joint
