    Caltrans Headquarters

    Thank you very much for the information. This was exactly what I was looking for.

    Caltrans Headquarters

    I am wondering if anyone has seen the show on the construction of the Caltrans headquarters. I saw it a few years ago but can not remember which channel issued it. It had some great sustainable design concepts I wanted to see again. This same building was in the last issue of Civil Engineering

    T&G Decking as diaphragm

    I have not found any literature on the lateral capacity of T&G decking. I always add sheathing on top of the T&G deck and provide the naling required. I assume that the deck is blocked when required.

    Masonry wall reinforcement

    I have done a very similar detail. I had a weldable rebar welded to the top of the beam. Make sure that you watch the deflection of the support beam.

    site built rafters for garage

    you should have a licensed engineer check the design. The members may work but it is usually the connections that fail first.

    Unheated Building with Slab-on-Grade

    I have used the Design Guide For Frost-Protected Shallow Foundations to design foundations for unheated pre-engineered buildings. Has anyone else used this design guide?

    Metal Truss Designs

    I agree, this is definitely a cop-out from the EOR. Who would be responsible for the design of the connection between the diaphragm and the lateral system (walls). The EOR should be responsible for the lateral transfer. And in the case listed above, wind may have been the controlling factor...

    Beam splice

    I would suggest that you try to avoid any moment connect through a wood connection. You would be better off running you deck joist back into the main span as described above by tfl.

    OSB wording on the plan

    I call for either osb or plywood as long as it is APA Rated. I also provide the span rating and nailing requirements (both in the field and on the edges and perimeter)

    Califronia framing

    California framing is no more than overbuild framing. It is just stick framing in the field usually over a trussed roof for a dormer roof like you mentioned before. As for the comment about it does not need to be calculated. You should always take the time to design everything for yourself to...

    Modal Law Structural Engineer

    Does anyone know where the term Modal Law Structural Engineer (MLSE) came from and what would be the benefits of registering with NCEES to become one? What does it really mean to become a MLSE versus a SE?

    Good Timber and/or Masonry Text

    I also agree with UCfSE. Breyer and Amrhein are great reference manuals. With the wood design, you should also consider getting the APA Design/Construction Guides: Diaphragms and Shear Walls and Residential and Commercial. It would be nice if Amrhein could put out one more great manual and...

    Structural II PM (Seismic) Exam (for Illinois SE registration)

    I know of someone who took the oral exam but it was about 20 years ago.

    Structural II PM (Seismic) Exam (for Illinois SE registration)

    The NCEES preparation manual is a good start. Do not just focus on steel and concrete, know all of your materials. The test is a written exam so be ready to give as much information as possible. Know your seismic design very well, it is the second part of the test.

    wind analysis software

    Does anyone have any recommendations for a software package that will obtain design wind loads for buildings in complete conformance with the IBC and ASCE7-98.

    shearwall pilecap

    You may want to consider contacting the geotechical engineer which provided the soils report, if one was provided. If you give them the axial and lateral forces, they should be able to provide you with the number and length of piles required to resist those forces. They will at least, as a...

    Floor Vibration Software

    I am looking for a software package that is windows based for analyzing floor vibration.

    Spreadsheets

    Does anyone know of any spreadsheets that are based on american units instead of SI units?

    Post-Tensioned Slab-on-grade Foundations

    Post tensioned slab on grade construction is common in the west coast. The post tension institute (PTI) has a design manual for a post tensioned slab on grade. You may also consider contacting your geotech, he or she could get you more information on other projects they may have down in that area.
