Mangaluru, May 6: According to an experts survey, it has been found that buildings in Bejai-Balmatta, Attavar -Hampankatta, have not adhered to IS 1893 : 2002, Part 1, which is the criteria for earthquake resistant design of structures, NITK?Civil Engineering Department Professor D Venkat Reddy said.

He was delivering a talk on ‘Earth, oceans and coastal zone management’, organised by Institution of Engineers (India) local centre an Institution of Valuers Mangalore Branch in Mangaluru.

The city falls in seismic zone-3 which means that the quakes of intensity six could occur. The buildings could withstand the earthquakes up to five in the Richter scale. As per Indian Standards on Earthquake Engineering, IS1893:1984 criteria for Earthquake Resistant Design of Structures, the country has been categorised into five seismic zones, based on the seismic intensity. IS is about earthquake resistant design of structures and is applicable to buildings, and other structures such as bridges, dams etc. Earthquakes of magnitude of eight take place in zone five. Nethravathi and Gurupur river basins are tectonically active.

As observed in Nepal, the structural failure of buildings have caused more amount of damage. In contrast, the Pashupathinath Temple is intact, though the building in its surrounding have been badly effected, which is due to the difference in structural pattern.

He further said that seismic waves alone are not responsible . Seismic activities take place round the clock. The earthquakes take place due to the sudden failure of strata. As per an estimation, around one thousand take place across the world everyday and three of them could be serious.

A lineament which is a fault in the underlying geological structure and the constructions on these lineaments such as railway tracks, bridges etc could cause more danger. IIS?has established a network system which records the seismic activities and which can even record 0.1 mm change in the crest of the earth. As per the movement of earth plates, a region will be displaced in a span of hundred years.

I'm building a 1story house with slab on load bearing walls instead of the concrete frame structure. Will this be resistant agaianst earthquakes?

Kalaburagi, Mar 7: Congress and JDS MLAs are eagerly waiting to join BJP, said former minister and chairman of Nijasharana Ambigara Choudaiah Abhivradhi Nigama, Baburao Chinchansur, here on Friday.

Speaking at a press conference here, Baburao said if the BJP top brass gives a green signal to include MLAs of other parties, both Congress and JDS would be almost empty. Many leaders, including D K Shivakumar and G Parameshwara, won’t support Siddaramaiah and the former CM will have to find his own way in the coming days, he predicted. He said Congress will not be coming to power in Karnataka for the next 20 years, he said.

Chinchansur thanked Chief Minister B S Yediyurappa for providing Rs 50 crore for Nijasharana Ambigara Choudaiah Abhivrudhi Nigama in the budget. He also said that a delegation will be taken to New Delhi under the leadership of the CM, after the budget session, to pressure the Union government to include Koli community in ST category.
