    Need literature for earthquake structural design

    The package is aprox NOK 200.000,- basic program, add-ons, maintenance etc. I only approached one Norwegian software supplier and the price is from memory and rough. The dollar being rather feeble right now gives a price a bit less than USD 40.000. Furthermore I don't believe the software...

    Need literature for earthquake structural design

    Thanks for your kind offer, drile007. I need to gather my thoughts and find some time before I can put a problem to you. I am not familiar with earthquake engineering. I was hoping there might be a book to hold my hand through the basics and then give a few examples. Some of our buildings are...

    Need literature for earthquake structural design

    Oh good, The review gave me the imprssion of it being rather hefty and suitable for advanced users who maybe want to bypass the codes. It costs USD 200 mail order, and I want to make sure it's suitable. My projects involve steel, concrete and sometimes timber structures. Buildings on the whole...

    Need literature for earthquake structural design

    Found a review of Telfords book. http://www.thomastelford.com/journals/DocumentLibrary/Eurocode%208.doc Seems like a heavy read, though comprehensive. Furthermore it needs to be read in conjunction with the code - Which I don't have yet. Anything simpler? Maybe a publication from an engineers...

    Need literature for earthquake structural design

    There is a Norwegian design code for the subject, but it will be phased out or adapted to the European codes soon. Naiem's book seems comprehensive abd a good buy, but it covers the US codes, and I would like to buy a book that covers the euro ones. Also feet, inches and pounds give me a hard...

    Heat insulation of steel connection

    Hi, Steel beam is to penetrate an exterior wall. Architect stated that there are special thingies to be bought to place in the beam to insulate the cold bit from the warm. I.e. a beam joint that reduces heat loss through the steel. Anyone heard of these?

    Quantify water infiltration through backfilled concrete wall

    Hi, Given a 350mm thick concrete wall, backfilled. The external water barrier fails and water pressure against the concrete is established. The concrete wall is uncracked. Up to 4m head of water. Inside is an archive for important documents. As consultants, we have been asked to quantify the...

    Foundation design for uplift during construvtion period

    The uplift per pad is in the order of 100kN, and the pad area 700x700mm. Height 300mm. Top of pad flush with backfill. That isn't a whole lot of friction. If the pad was an empty tub I could lift it myself. There are however 4 large pads, one per side, to anchor the wind bracing in. If the wind...

    Foundation design for uplift during construvtion period

    I spoke to the person behind the standards, and the following was his way of thinking: For a 50 year life span: During any one year there should not be a greater than 2% probability of design wind being exceeded. My understanding is: If construction time is three months, I need to ensure that...

    Foundation design for uplift during construvtion period

    Sorry, I don't seem to have stated that the uplift would be due to strong winds. The customer changed his mind again. Small pads, his responsibility. Man, I'd like to know of a case where a building took off due to insufficient anchorage.

    This is probably what I'll end up doing. But I really want him to accept my big pad solution. Others do.
