Hello
Please help me to find the staad command to apply a point load on beam when coordinates (x, y, z) of load are known. I need to apply it on a curved beam. Have been tried member load already but its not working positively.
Request you to please guide me to apply load command when coordinates are known.
Regards
Ravi
Hello Ravi,
In the Technical Reference Manual chapter 5.20.8 is noted:
"Currently, two load types are permitted on curved members. One is the SELFWEIGHT load type, described in Section 5.32.9 of the STAAD.Pro Technical Reference manual. The other is the uniformly (UNI) distributed load type of the MEMBER LOAD options explained in Section 5.32.2 of the same manual. The uniformly distributed load has to be applied over the full span of the member. Other member loads such as LINEAR, TRAP, CONCENTRATED force or moment, UNIFORM moment, etc. are not currently supported."
This is only one of some more limitations for curved members. Due to all limitations, I think that modeling the curved beams using a series of straight segments might be a better option and then You would be able to apply the concentrated force on those beams.

Hello Modestas
Thanking you for immediate useful response. Still i am stuck on same level for analysing curved beam. Kindly suggest the method to run live load on curved beam.
Hi Ravi,
I would still suggest you using straight lines to simulate the curved member. On straight segments, You should be able to apply any loading.
Hi Modestas
As per your suggestion, Span should be bifercated in several straight members putting respective node on curve path. But that will not be sound engineering analysis. Request you to please suggest me suitable steps. In India, futher authorities will not accept this kind of assumption. So i need to model accurate as per reuirement.
Sorry, I am not able to think of any other way to apply concentrated load on a curved beam in STAAD.Pro. Maybe someone else in this forum could suggest you a better way.
