It is to serve this purpose that IS 1893 : 1962 ‘Recommendations for earthquake resistant design of structures’ was published and revised first time in 1966. … In the clauses for design of multi-storeyed buildings, the coefficient of flexibility was given in the form of a curve with respect to period of buildings.
Is 1893 1984 criteria for earthquake resistant design of structures?
5 Page 10 IS t 1893 – 1984 a structure which is properly designed and detailed according to good con- struction practice, will not suffer serious damage. It is pointed out that structures will normally experience more severe ground motion than the one envisaged in the seismic coefficient specified in this standard.
Which of the following is code explains criteria for earthquake resistant design of structures?
Today, the Bureau of Indian Standards (BIS) has the following seismic codes: IS 1893 (Part I), 2002, Indian Standard Criteria for Earthquake Resistant Design of Structures (5th Revision) IS 4326, 1993, Indian Standard Code of Practice for Earthquake Resistant Design and Construction of Buildings (2nd Revision) IS 13827 …
Is codes for earthquake resistant design?
The list of Indian standard codes for earthquake design of structures include IS 1893–2002, IS 4928–1993, IS 13827–1992, IS: 13920–1997, IS: 13935–1993. … These codes are the guidance of designers to plan, design, detail, and construct buildings to withstand earthquakes.
What should be the design of earthquake resistant houses?
Earthquake-resistant building designs consider the following characteristics that influence their structural integrity: stiffness and strength, regularity, redundancy, foundations, and load paths.
What is seismic zone coefficient?
Each zone has a seismic zone coefficient (Z) which represents the maximum considered peak ground acceleration (PGA) on very stiff soil/rock (site class SA) in units of g (acceleration due to gravity) The northeastern folded regions of Bangladesh are the most active zones and has a maximum PGA value of 0.36 g.
What is seismic zone factor Z?
Seismic Zone Factor (Z):
It is represent the peak ground acceleration in studied site as a percentage of gravity. acceleration g (9.81 m/sec2).
How do you calculate earthquake load?
The lumped weight due to dead loads is 12 kN/m2 on floors and 10 kN/m2 on the roof. The floors are to cater for a live load of 4 kN/m2 on floors and 1.5 kN/m2 on the roof. Determine design seismic load on the structure as per new code.
Is code for steel structure?
Indian standard code for structural steel design for all types of structures are given below. IS:816 : 1969 – Code of Practice for use of Metal Arc Welding for General Construction in Mild Steel. … IS:1161 : 1998 – Specification For Steel Tubes for Structural Purposes.
How deep is a shallow earthquake?
Shallow earthquakes are between 0 and 70 km deep; intermediate earthquakes, 70 – 300 km deep; and deep earthquakes, 300 – 700 km deep.
What is earthquake resistant design?
Earthquake-resistant or aseismic structures are designed to protect buildings to some or greater extent from earthquakes. … This means the loss of life should be minimized by preventing collapse of the buildings for rare earthquakes while the loss of the functionality should be limited for more frequent ones.
Is 800 a steel code?
IS 800 is an Indian Standard code of practice for general construction in steel. The earlier revision of this standard was done in year 1984 and the latest revision of 2007 was released on 22 February 2008. It is written for use in India.
Which is code is applicable for earthquake design?
As an adjunct to IS 1893, IS 4326 ‘Code of practice for earthquake resistant design and construction of buildings’ was prepared in 1967 and subsequently revised in 1976 to be in line with IS 1893 : 1975.
Which is the most earthquake resistant structure?
These 7 quake-resistant buildings are designed to withstand the next big shockwave
- Shanghai Tower in Shanghai, China.
- The Transamerica Pyramid in San Francisco, California.
- Mori Tower in Tokyo, Japan.
- New Wilshire Grand Center in Los Angeles, California.
- Sabiha Gökçen Airport in Istanbul, Turkey.
What is the best shape for an earthquake proof building?
“You will see that the Dome is by far the strongest shape when it comes to earthquakes.
What is the safest place in your house during an earthquake?
You are safer under a table. In modern houses, doorways are no stronger than any other part of the house. Doorways do not protect you from the most likely source of injury − falling or flying objects.
