Thank you all. @Retired13-This is going to be used as a typical drive through parking garage.

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...

Hi, I have been asked to review an existing two story wood structure which is about 100 years old. The client's intention is to use the structure for parking facility. IBC load requirement is just 40lb/ft2. I tried to find some design guidelines for parking garage, but could not. I do not...

Thank you all.

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.

Hi, In ASCE 7-10 there are 2 ways to calculate wind forces on buildings. Directional method and Envelope method. 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...

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...

Hi, I am assigned to design an underground tank, which connects into two other large underground tanks from both sides. All together, they are going to be in a straight line and the distance from one end to the other of interconnected structure would be about 500 ft. The one that I am going to...

It is an interesting topic. In my construction experience in some Asian countries, a thin layer of concrete is used underneath the structural foundation, which is called screed. This is usually made with Grade 15 or 20 concrete (2200 psi or 2900 psi). The thickness varies depending on the...

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...

Well, Thank you all for your kind advises. Based on your responses, I think, it is better, safer and saving my time rather than taking this job and asking for future troubles.

I have a client who wants me to prepare shop drawings for his building project. It is a steel structure with about 3500 sq.ft. floor area. I am a licensed P.E. in structures. But I have never prepared a shop drawing. Therefore, I have the following questions: 1. Should the shop drawings be...

Hi, I am new to this subject, but am designing a 125*100 foot rectangular foundation on expansive soil (with post-tensioned slab on ground with ribs in Houston, TX. PTI-DC10.1-08 gives several design examples for Extreme dry, Extreme Suction profile and wet climate. Do I have to do the design...

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.

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]
