I cannot generate a floor load for groups which i created.How can remove the warning "NO MEMBER LOAD FOR FLOOR LOAD GENERATION" ,without intersecting the beams.
build.stdstaad warning
There are few modelling problems. There are beams which are running without a connection to the other beams. You can simply resolve the problem by selecting all the members and then, going to Geometry> Intersect the selected members. Please refer to the attached model. You need to create floor groups with beams forming enclosed planes. Beam groups where you want to apply Wind load should follow the same rule.

build 1.stdThanks.
But when intersecting beams it's length become very small(<1m).So in design part warning came as " lenth to depth ratio is small."
There are some warning in the design:
WARNING:LENGTH TO DEPTH RATIO FOR MEMBER … IS LESS THAN 2.5”
Deep beam is not designed in STAAD. Thus whenever a beam is sub-divided into many sub-beams or you model a beam of small length , then L/d ratio is decreased since in this case length (L) is the length of the sub-beam and not the whole length of the beam extending between two columns. Thus a warning message is thrown to let the users know about the fact. In this case ordinary shear check will be performed.
I would suggest that you use ENSH 1 parameter for those beams where the program reports L/d is less than 2.5 to ignore enhanced shear strength. I have used the following commands in your model.
ENSH 1 MEMB 153 165 175 181 201 213 223 229 249 261 271 277 -297 309 319 325 349 359 365 390 399 405 460 462 466 469 483 485 489 -492 506 508 512 515 517 523 529 531 535 538 551 556 559 569 571 573 -576 585 588 590 592 594 595 596
