How many parts does 1893 have?
high value of natural period and thus low seismic force. The fourth revision of the code (IS 1893 : 1984) covered buildings, water tanks, stacklike structures, bridges, dams and retaining walls. When carrying out the fifth revision, it was decided to split the code into five parts.
Is 1893 code is used for?
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 Old Code?
The earthquake resistant design of structures taking into account seismic data from studies of these Indian earthquakes has become very essential,. It is to serve this purpose that IS : 1893-1962 ‘Recommendations for earthquake resistant design of structures’ was pub- lished and subsequently revised in 1966.
Is 1893 water tank?
According to seismic code IS: 1893 (Part 1)-2002, more than 60% of India is prone to earthquakes. Elevated water tanks consist of huge water mass at the top of a slender staging which are most critical consideration for the failure of the tank during earthquakes.
Is 1893 a load combination?
For IS 1893:2016, the maximum load combination factor is 1.5 and for NBC 105:1994 the maximum load combination factor is 1.3.
Is 1893 to 2002 give details on?
Explanation: IS 1893-2002 gives the criteria for earthquake resistance design of structures. It is the fifth revised edition.
Is 1893 a damping ratio?
The program will calculate natural period as per Clause 7.6. 2 of IS:1893(Part 1)-2016. Damping ratio to obtain multiplying factor for calculating S a/g for different damping. If no damping is specified 5% damping (default value 0.05) will be considered corresponding to which multiplying factor is 1.0.
What is impulsive and convective pressure?
The hydrodynamic pressure induced by earthquake can usually be separated into impulsive and convective terms. The impulsive component is governed by the interaction between tank wall and liquid and is highly dependent on the flexibility of the wall while the convective component is induced by slosh waves.
Is 1893 2002 give details on?
Is Uttarakhand earthquake prone?
The State of Uttarakhand has however not experienced a great earthquake (Mw ≥ 8.0) for more than previous 200 years and constantly accumulating strain thus remains due for release in this sector. The region is thus shown as falling in the seismic gap of 1934 and 1905 great earthquakes (Yeats and Thakur, 1998).
What are the five parts of is 1893?
Hence, IS 1893 has been split into the following five parts: Part 1 General provisions and buildings Part 2 Liquid retaining tanks — Elevated and ground supported Part 3 Bridges and retaining walls Part 4 Industrial structures including stack like structures Part 5 Dams and embankments
When did the Indian seismic code is 1893 come out?
The Indian seismic code IS 1893 has now been split into a number of parts and the first part containing general provisions and those pertaining to buildings has been released in 2002. There has been a gap of 18 years since the previous edition in 1984.
What was the fourth revision of is 1893?
Other parts of IS 1893 (Foreword, page 2) The fourth revision of the code (IS 1893 : 1984) covered buildings, water tanks, stacklike structures, bridges, dams and retaining walls. When carrying out the fifth revision, it was decided to split the code into five parts.
What are the assumptions in the is 1893?
Assumptions in IS 1893 –Part 1 1.Resonance will not occur during earthquake as the force is random & impulsive, not steady state. 2.Earthquake does not occur simultaneously with maximum wind, flood or sea wave. 3.Static properties (modulii, strength etc.) represent behavior during earthquake.
