I need a program for construction calculation, which provides process of construction. In the first phase, members are coupled without having flexural rigidity and in this manner transfer a part of load. In the second phase, members are coupled stiff and transfer the next part of load. Does anybody know a program, which alows to change type of connection between members ( cancel joints between members for any phase ) ?

Hello all!

We should have one seperate sub-section within SOFTWARE section for PORTABLE SOFTWARE. Nowadays there are large no of options (softwares) for a particular task (say PT,Bridge,Raft,Building design). Some softwares are used occassionaly. We can not install all these software at the cost of disk space and memory. PORTABLE SOFTWARES are best solution in such condition. aso we can use it by USB drive.

If we have seperate section, we don't have to browse old threads when we need any portable versions.

Thanx.

Dear Admin,

I'd like to share my opinion. We should have one section for collection of old software such as software run on DOS, win95, win98. The word "museum" is worth for people who love antique stuffs. Some programs which run on DOS have the same core of analysis of the present software in the market now. The interested issue is "nobody" caring about copyright. Some situation we can use this kind of software officially. I also had used analysis program to analyze the frame and take the results into structural design with Excel.

I hope there will be members agreed with this idea.
Thank you.

Best Regards.
