Different Failure Modes of Concrete Columns – Compression Members
There are three modes of failure of concrete columns (compression members) i.e. failure due to pure compression, combined compression and elastic instability. These modes of failures of concrete compression members are discussed.
Methods of Splicing Reinforced Bars
Most of the reinforced concrete structures won’t be provided with full length reinforced bars. The manufacture and transportation of long bars are difficult, which limit the use of full length reinforced bars. The method used to join the reinforcement bars, ...
Balanced, Under-Reinforced and Over-Reinforced Beam Sections
Reinforced concrete beams are classified as balanced, under-reinforced and over-reinforced based on its reinforcement percentage. Details of these beam sections are discussed.
Durability of Reinforced Concrete in Different Environmental Conditions
Durability and strength are two most important criteria for the design of reinforced concrete structures. These are the two requirements for the long term performance of concrete structures. Any deficiency in any of the two i.e. durability and strength, could ...
Typical Joint Detailing of Steel Hollow Sections -Types of Joints
Typical Joint Detailing of Steel Hollow Sections Detailing of joints in steel structure is as much important as detailing of main structural members. Ultimately loads from structures are transferred to different structural members through joints. So, a good detailing of ...
Different Types of Machine Foundations and their Uses
Machine foundations are special types of foundations required for machines, machine tools and heavy equipments which have wide range of speeds, loads and operating conditions. These foundations are designed considering the shocks and vibrations (dynamic forces) resulting from operation of ...
CONCEPT OF REINFORCED EARTH STRUCTURE DESIGN
Reinforced earth is a composite material formed by the friction between the earth and the reinforcement. By means of friction the soil transfers to the reinforcement the forces built up in the earth mass. The reinforcement thus develops tension and ...
