    spectrum damping for modal analysis

    Sirs: It seems that SAP escalates the earthquake spectra for different damping values. If I enter a 5% damping spectra and due to internal calculations of SAP (for example if I use material damping) the modal damping of some mode results,say 8%,the program needs to escalate the spectra. Does...

    Seismic accelerations in SAP

    Sirs: When SAP 11 and 14 is used for Seismic Modal Analysis there is an option to recover accelerations in different nodes. Option is called "Joint output acceleration", within "show tables". Sap presents two alternatives: Absolute and Relative accelerations.When the option is used always...

    Bending moment on braced legs for horizontal loads.

    Tom: Thanks for your reply.Please comment following points to be sure that I understood properly your communication: a)If somebody uses the y'parameter, "vertical offset distance" (page 12-15 of Compress Help Manual) Compress stress analysis of the leg will not account for the bending moments...

    Bending moment on braced legs for horizontal loads.

    Dear Sirs: I am reviewing a seismic analysis of a vessel supported on four legs done with Compress. The legs are X braced ;the bracings are located at midheight of the legs.Thus,below the bracings and above the bracings there are segments of legs that are submitted to bending due to the...

    Computer graphics tools

    Sirs: The application shall be standalone , in C++ or Fortran, Windows. I am looking for tools that enable me to insert graphic code for my GUI.I dont knoww if exists some tools for doing this.Perhaps there are some programs that I can embed in my code.A sort of 3d graphic engine that can...

    Computer graphics tools

    Sirs: I am looking for software graphics tools for developing an engineering application. The applic. considers an GUI for creating 3D models using simple geometrical shapes. Once entered the solid model the software performs some numerical calculations and presents the results. Are such...

    B31.3 Acceptance criteria issues

    Thanks again John for your valuable comments.During the weekend I thought again in the problem.Some of the conclusions (perhaps very elementary) are the following ones: -The B31.3 code presents a civilized way to do risky projects that involve piping lines.For this ,the code stablishes ways to...

    B31.3 Acceptance criteria issues

    Thanks John: I agree with you.But here (in Chile),there is a discussion in this issue.A client says that the Acceptance Criteria (AC) asks for "no unfilled areas,no unbounded on joints" in absolute terms.What I think (and also you it seems to me),is that the concept is that "The AC is...

    B31.3 Acceptance criteria issues

    Sirs: For nonmetallic piping,Heat Fusion Bonds the ASME B31.3 Acceptance Criteria requires non unfilled and unbounded areas.OK.But wich is the MANDATORY examination that the erector have to perform to accomplish this,in case that the contract only indicates that the piping shall be according...

    Coupled Model for tank seismic analysis

    Sirs: I am planning to use a FE coupled model to analyse a large tank for seismic forces,incorporating the tank contents. Some multiphysics computer programs,such as ADINA,have the capabilities of using fluid elements combined with normal stress analysis FE.¿Does anybody has experience on...

    ADINA multiphysics

    Sirs: I am preparing the seismic design criteria of a very large bottom supported tank.Due to the size and importance of the tank I am thinking to use a coupled FE model that incorporates the tank and its contents.With such a model the hidrodynamic interaction I hope will be best accounted...

    HDPE Field inspection company

    Thanks ApC2Kp.I will contact Mcelroy but following issues persists: -In Chile sometimes old fusion equipment is used. -We know of some leakage problems of an HDPE line visually inspected.With environmental consequences due to the sulfuric solution inside pipes.That is the reason that mining...

    Graphics Software

    Sirs: I am looking for a software package that allows the following: -I have a library of about ten typical steel towers models. -Another library with 20 typical antennas. The software shall be able to a)show a solid model of the towers,allowing rotations of the models and b)to pick any...

    Loosening bolt shear connections

    Sirs: This is a typical problem that presents in telecom towers.I am refering to standard shear connections such as between diagonals and goussets.These connections are not slip critical and get loosened by the tower vibrations. Eventually the bolts fall down.My interest is to knoww an easy...

    SAE 4041 galvanizing

    Me again.Thanks Nicke;I found all discusions on this question.My question is if in general terms which "normal" steel have less problems in hot dip galvanizing embrittlment:SAE 4041,1045 or say 1020?Shall I avoid SAE1045 in my anchor bolt design? Capa.

    SAE 4041 galvanizing

    Thanks all.Do you think that the same happens with SAE 1045 steel? Capa.

    SAE 4041 galvanizing

    Sirs: Does anybody knows if there is a problem to hot dip galvanize SAE 4041 anchor bolts.I have an opinion on this that says that this treatment reduces strongly the strength of the bolt. Thanks,Capablanca.
