    Parking garage analysis and design

    Thank you Lomarandil and Dik for your replies. Your reply also pointed into a good point - connections. I may need to pay more attention on it again. Because this structure is located in coastal area, I am not sure of the connections are still in good condition. Further, lateral loads such as...

    DaveAtkins Thank you for your reply. My building is rectangular, but in two different roof heights. Each part is also rectangular. Roofs are flat. In that case, can I still use it as a single building? See below.

I am using Envelope method for one of my designs which is 56ftx53ftx24ft height flat building. Per ASCE, p = qh[(GCpf) – (GCpi)] (lb/ft2). If my building is partially enclosed, rigid...

    Differential Settlement of Interconnected Structures

    Jed, Thank you for your quick response, it helps me a lot. Yes, there are pipes connecting each tank. Bigger tanks are going to be pre-stressed (designed by someone else). As I understood, i would be able to use a exp. joint. However, if the relative settlement will be higher depending on soil...

    Structural Engineering Cost for Foundation Design

    Hi, Does anybody have an idea of how much a structural engineer should charge to design a foundation only for a residential building in TX? I am asking $ per square foot for a slab-on-grade. Does it depend on what kind of foundation or what kind of soil it is? (I guess not). In my case, it is a...

    Drilled Pier Foundation on Expansive Soil

    I also saw that. But, I wasn't sure if a church would fall in a different category, as it has the requirement that seats to be fastened to the floor.

    Drilled Pier Foundation on Expansive Soil

    Yes. That is why I wanted to go for a highwe load which is 100psf, ven though not listed in the code as a church. But was little doubtful, if I did was right, when looked at the pier dimensions required. [bigsmile]
