What is Elasticity
Elasticity is a central concept in economics, and is applied in many situations. Basic demand and supply analysis explains that economic variables, such as price, income and demand, are causally…
SEISMIC EVALUATION AND RETROFITTING OF BUILDINGS AND STRUCTURES
Concrete has been the most preferred construction material of the twentieth century, and unless a new material with spectacular characteristics is invented, it appears poised to remain this way for…
METHODS OF ANALYSIS FOR EARTHQUAKE FORCES
Seismic analysis is related to calculation of the response of a building or other structures under earthquakes. It is a part of the process of structural design which includes earthquake…
Earthquake demand
The first step is to determine the earthquake demand on all of the components that make up the engineering systems within the building. This is the procedure to determine earthquake demand:…
SEISMIC RESPONSE CONTROL SYSTEM FOR NUCLEAR REACTOR BUILDING
The conventional nuclear R/B is primarily made of a reinforced concrete (RC) structure. The shape of this structure is almost cubic and the length of each side is approximately 60m,…
What is a ductility?
Ductility is a measure of the material’s ability to undergo plastic deformation without breaking. Ability to be drawn into wires (from the rod stage) is an example. The area under…
LOAD COMBINATIONS
Because various loads may act on a structure simultaneously, load combinations should be evaluated to determine the most severe conditions for design. These load combinations vary from one document to…
EARTHQUAKE RESISTANT STRUCTURES CODE PROVISIONS
India is considered to be one of the most populated countries with an average population of 382 persons per square kilometer. India is among one of the most disaster prone…
Effect of Infill Walls on Structural Frames
Abstract— In the building construction, framed structures are frequently used due to ease of construction and rapid progress of work, and generally these frames are in-filled by masonry infill panels…
EARTHQUAKE-RESISTANT MASONRY BUILDINGS
Masonry is the most important construction material in Iran. It has been used for public and residential buildings in the past several thousand years. A great number of well-preserved old…
