    Large diameter (10+m), High Pressure (10+ bar) Steel Vessels

    Is it possible to design high pressure, high diameter steel vessels? I know nuovo pignone do some really high pressure vessels with diameters up to 8m but they are all very long. What sort of size are nuclear containments? Can you resist circa 10+bar pressure & temperature with welding? I'm...

    Bolt design to Eurocode

    Does anyone know how to design bolts in concrete to the Eurocode? I am looking through EN1992 but can't find formula on anchorage bond stress etc, can I just treat it as a reinforcing bar (and use EN 1992-1.1 clause 8.4.2)? I also have to check punching shear which should be ok... Any help...

    Increasing the dead weight of your concrete

    Does anyone know of a way to cheaply increase the weight of concrete? Its not a strength issue so I don't want to increase the grade or anything. Are there certain aggregates that increase the weight without affecting the grade? Any help would be appreciated! ...apologies, i initially posted...

    Damping coefficients for ground types (seismic engineering)

    Can anyone explain to me/point me in the direction of some good resources on damping coefficients for different ground types? I know the waves propegate differently through different material & if you are on a soft ground your loading will be more severe than if you were on rock...and that say...

    Pay Cut - other benefits

    We are being asked if we would consider pay cuts as part of the effort to avoid redundancies - obviously they can't force us to as our wages are part of our contract, and its not even us necessarily at threat in the redundancys. I don't mind taking a pay cut in terms of hours worked but its...

    Job situation in the US

    I'm just curious how the job situation is looking in the states for civil/structural engineers? Theres a lot of infrastructure work that needs doing - bridge inspection work etc but is this coming through & what are other areas like? Obviously housing is fairly bust but are there...

    Bearing alternatives

    Anybody got any recommendations on alternatives to traditinal elastomeric/mechanical bearings allowing lateral movement while taking significant axial force? Its approx 300mm of movement and its a one off (slow occuring) event. Its two concrete surfaces so i was thinking there may be away for...

    Reducing friction coeff of concrete

    Anybody got any suggestions on suitable coatings/paints for contact between two concrete surface? The codes seem to indicate you have to take a coeff of between 0.5 and 1 (when its beneficial) - i need to reduce that somewhere below 0.3, which is prob the max i can get away with. Theres a...

    Thermal Movement in Concrete/Steel Curved Composite Structures

    Is there a difference in how a curved section of a bridge reacts to temperature change as oppossed to a straight section? If the bearings are articulated to allow movement around the curve does it effectively behave in the same way...?

    Limiting stress value for steel beam flanges in composite sections

    When looking at a steel concrete composite section you need to calculate the build up of stresses in the extreme fibre of the steel beam's flange. This is relevant under hogging moments but im not 100% sure why. What sort of failure do you get when the yield stress is reached in the flange? Is...

    Essential Reading for Structural Engineers

    I'm just starting out working life as a structural engineer having recently graduated and was wondering if anyone had had any advice on 'must read books for structural engineers? I'm particularly interested in any slightly less technical books that will improve my overall understanding & knowledge!

    What exactly is Shear Lag?

    I am currently working on modelling of an existing steel concrete composite bridge (RC deck atop Steel UBs) and understand shear lag reduces the effective width of the sections but could do with understand what exactly it is, why exactly it occurs and when it needs to be considered if anyone...
