Concrete Roof Slab with no decking.

I have a concrete roof deck that I need to check for its capacity to support a swing stage. The load will translate to a point load at two points along the concrete roof deck. What is the area I can distrubute this load over? Is there any way to better distrubute the load over a larger area...

I am currently working on some interior metal stud framing. The framing is suspended from the metal deck above around the perimeter. The contractor is utilizing 12 gage steel tie wire (@48" c/c) to help support/ suspend the interior ceiling members. Does anyone know the allowable tension for...

I am currently designing a glass railing consisting of an aluminum shoe and 1/2" tempered glass. I determined wind pressure requirementss based on ASCE 7-05 "solid sign" and the loads are coming up very high. 75 psf for a railing at an elevation of 30 ft. (140 mph) Since this is not really a...

unfortunately the design pressure requirements are as per engineer of record.

The wind pressure here in south florida is based on 3 sec gust. Short term loads

I do have a copy of Rourk's equations. Which tables shouls I use. Since it is poin supported I am not sure of the boundry conditions.

I don't think its an option. It will have to be laminated glass. Are you thinking 3/8" lite laminated to a 1/4" lite?

I have the window glass design software using ASTM E-1300. When I ran the glass as a two sided support for the 80" span with 9/16" tempered laminated glass. The program said that it would not work. It just seems like it should for a design pressure of 65 psf.

Any advise on which finite element software?

The 100 psf load over one sq. ft. is meant for a safegaurd.

In roark's Table 11.4 (1c) is uniform distibuted load over a small central rectangle. Thiss is a 100 psf load over a 1' x 1' area

Unfortunately I don't have access to finite element analysis software.

Its a square pattern 1" c/c 3/4" square holes

I am analizing a glass canopy that is point supported. All of the ASTM E1300 tables/ software call for four or two sided support for glass analysis. Any ideas on how this should be done? It is 80" x 70" (9/16" laminated glass) with (3) point supports at ea. end of the 80" length and is...
