Hello all, I have been trying to model a truss. I have two bottom support, it can be fully fixed or partially fixed and I have two cable connection at the top. But this cable member should not take any compression, since I have Wind suction in that…

Good morning, I have problem with my steel truss bridge design, i've used member specification release MY;MZ and truss. Then this message came after i am running the analysis. ***WARNING - INSTABILITY AT JOINT 490 DIRECTION = MZ PROBABLE CAUSE…

Hello All, I have modeled a simple steel truss to check my hand calculations. When viewing the global status of the model, the diagonal members are shown to have "Errors in Design." The members all have ratios from 1.84 to 3.6. However, my…

I am using RAM Element Truss design Module. When viewing the report it says the one RXN is zero. the truss is symmetric so the RXN should be similar?

Hello, I am working on a structure and having issue when define member truss the actual ratio is showing 94.9E24. Please have a look on attached staad file. STAAD_600MW.rar

I have read, all the related forums & watched tutorial videos. i have designed the truss by a] by truss specification Done by truss specification.std and b] by partial moment release .99 Done by partial moment .99.std First of all, im…

I assigned a uniform load in Kip/ft on a truss. However, the report shows up kip/in. I haven't run the numbers but may be this is something to look at. PDF
