    H1B jobs nowadays: more or less requests?

    Are USA still searching for H1B jobs nowadays? Do you think the request is changed? Decreased? Maybe increased? In particular, what about structural engineers from other countries? Are you (Americans and foreigners) experiencing problems when searching for a job? Thank you for your answer...

    moment frame investigation

    This isn’t only strange, it is an error. When you design a MRF building (Moment Resistant Frames) you must consider horizontal loads and vertical loads, because the axial force given by DL will reduce the moment resistance. You can easily see it if you consider a M-N domain, in which you can...

    clarification on modal analysis

    Yes, as said by lisica you can perform a modal analysis to know how your structure vibrates. A multistory building is a M-DOF system, with M > 1. If you have a 10 stories building, you will have a 30 degree of freedom system (if you have a rigid diaphragm, so you get 3 dof/story x 10 stories =...

    When is P-Delta Calculation required?

    You can always check P-delta effects, but in some cases it is really necessary to do it. If you consider a cantilever beam with vertical P force and an horizontal one, this last will give you a displacement equal to F H^3 / 3EI, so you will have: Mtot = F H + P (FH^3/3EI) = F H [1 + (P...

    other options

    The Moment Resistant Frame Solution isn’t the best you can have due to its deformability (deformability check could coerce you to increase sections dimensions) and for huge detailing. But has a good ductility. So you can choose a Braced Frame solution. If you go for CBF (Concentric Braced...

    Rigid diaphragm?

    How can you judge rigidity from a schematic figure? Check your code, you will find the correct dimensions and detailing to define a diaphragm as rigid. For example, if you give a look at Eurocode 4 - Design of composite steel and concrete structures, you’ll find minimum requirements in order...

    Italian engineer in USA

    Hi all, once again, firstly I would like to give my thanks to cry22 for his tip on Beppe Severgnini’s “Un italiano in America”. He is an Italian writer who worked for The Economist and wrote this book on his experience in USA, where he lived for 1 year (spring ’95 to spring ’96). I read it...

    Italian engineer in USA

    Meanwhile, i've done some research. Seems that USA Government wants to rise up the H1B number (up to 140 000). I hope that an engineer and a biologist won't have problems getting one. I'm very curious about USA engineers, about their know-how level. I hear that USA education isn't so perfect. I...

    Italian engineer in USA

    Hi all, I'm a junior structural engineer (3 years) and soon i'll become full engineer (5 years). I study at Federico II of Naples (ITALY). I have a dream: go to work in USA. And this dream could become true in january 2009. Have you any tip for me? Do you think an italian engineer could find...
