I have found some answers, but please let me know if I made mistakes in my conclusions. After I discuss with some of my friends, maybe I could conclude some point about the slenderness limit rule. 1. As long as the structure's failure is not decided by earth quake, especially in large...

Hi,all... I need your opinion. I'm debating with my co-worker about the slenderness effect on compression member. My opinion is that we should fulfill the slenderness requirement for compression member which is k*l/r > 200. Neglecting the slenderness may cause sudden failure for the component...

Hi, I desperately need your help. I'm currently doing cylindrical compressive strength on concrete with according to ASTM procedure. As far as I know, the minimum compressive strength of the concrete on 7th day should be at least 65-70% from the strength. In my calculation, I'm using concrete...

@ToadJones It's true that the crane load design is supposed to be more complicated than designing the wind load, but in the process, I have a very good guide book (which is CISC - Crane Supporting Steel Structure) which help me a lot not to mess with the crane load. I agree that the crane load...

Ah, it really explain why I messed up with the wind since I apply the wind load factor as drag factor (which is said by mr. patswfc to be small). Btw, I kinda confused since the building is L shaped, then there should be turbulence in the inside corner of this L shaped building. Can someone...

All, I need some correction, please correct me if I'm wrong. In designing wind load on structure, I have Wind Factor (according to my Country's Code) +0.9 for inward surface, -0.4 for outward surface, and -0.4 for parallel surface. Now here comes the problem. The wind factor for the parallel...

@hokie66 & Mike : I totally agree with you. But, the fact that I don't get decent mentoring can't be changed. Truthfully, we are less experiences in this kind of project since we usually works on Jetty , Dolphin, and other marine structure. That's why I don't get decent mentoring from my seniors...

Hi all, I beg anyone who could help me sharing some tips in designing a manufacture building especially in resisting wind load. This is my first time designing a very widely wind exposed building. Currently I am working on a steel pipe rolling mill building project and I found difficulty with...

Hi all. I really need your help please. I want to ask about CISC Design guide for Crane Supporting Steel Structure. It is written in table 2.1 about "Crane Vertical Load, Side Thrust and Tractive Force as Pecentages of Respective Load" that the Total Side Thrust (two sides) is Greatest of ...
