Since I haven't solved a tall structure like in the attached project, I'm waiting for friends' comments on data entry and results. How should I model the elevator pit? Note: I couldn't solve the ladder with the structure even though I edited the Support conditions (editing was reversed in the project). The landings that I created with the slab edge are my problem. I seek help from those who have time. plugin: http://rapidshare.com/files/2964305725/A-BLOK%20STAT%C4%B0K.ide7
