Thanks JAE, It's definitely not a closed-form solution. To others who thinks this thread looks familiar. Sorry, I accidentally copied and pasted this from a thread I submitted last week. Sorry about that; I didn't mean to duplicate it. Your suggestions on how to approach it over on the...

Thanks to all of you who have replied to my thread; I really appreciated your thoughts and ideas on how to approach this problem. There were a lot of good suggestions there. I think the bottom line is that it's not an easy problem. I'm trying to solve the problem by taking a dynamics approach...

Hi, I'm carrying out a debris scenario analysis for a structure subject to seismic loading. To expand, there is a steel-framed loading bay that temporarily stores steel containers containing hazardous material before the containers are moved to a more permanent home inside a reinforced concrete...

I need some help. I'm carrying out a debris scenario analysis for a structure subject to seismic loading. To expand, there is a steel-framed loading bay that temporarily stores steel containers containing hazardous material before the containers are moved to a more permanent home inside a...

Thanks SethGuthrie for your reply and thanks to your colleague too. It's a bit disappointing that STAAD has decided to limit rebar design in this way but I suppose it's better than no design at all. I suspected that this was the case but I hoped that I was wrong.

Hi Edward. Thanks for that. I ended up doing it the way you suggested and it worked. Still, it would nice to know if there was a way to do it without having to "trick" STAAD into designing the correct reinforcement. If I have a more complicated structure such as a frame with horizontal...

I'm currently trying to obtain STAAD output to obtain adequate reinforcement for a concrete beam. I've sort of been able to do this but unfortunately, it's not designing the rebar based on the predominant force that I've applied to the beam. My problem is that the predominant force is applied as...

Thanks again for your continued contributions guys; it's really helpful. I thought I'd give a little more background and clarification into what I'm trying to achieve with my model. Here's what I've got; There is large tank filled with liquid inside an enclosure with a RC wall around it. If...

Thanks for the replies. JoshPlum, that's disappointing that I might not be able to do this type of analysis with STAAD since I've burned quite a few hours in the budget already building the model. That'll teach me to start off with a simple model to test out the features of unfamiliar...

I'm unsuccessfully trying to analyse a frame that is subjected to dynamic fluid loading. I'll describe the structural problem, how I want to model it using STAAD and why I don't trust the output. I'd welcome any suggestions on how I can get it to work or if STAAD just isn't up to the job. I...

I'm involved with compiling a scope of work for carrying out a periodical survey of the piles of a jetty to acertain their structural integrity. The jetty has a total of about 250 piles. Obviously, it's impractical to inspect all of the piles due to time constraints and difficulties associated...

Yes, I did look at the link that you sent me this morning. I saw a list of forums dedicated to specific software packages. As I've said, my query wasn't specific to a particular piece of software. It was a general enquiry asking for advice on which software would be able to perform a...

Thank you so much rowingengineer. I'm going to try both of your suggestions and see which works best for me. You may have saved me weeks of extra work.

I don't really have a specific structural analysis program in mind. As to which forum would be most relevant for me to submit my post, I wasn't sure about it and I'm completely open to suggestions.

The way I've been trying to do it so far is to use Excel. This is proving to be a very time consuming error-prone exercise. Unfortunately, the geometry is quite complicated and the number of pieces that I need to chop up each element into varies throughout, so a programming solution seems...

I have been given an existing simplified model of a structure. The important information consists of node position and member locations (i.e, the nodes that define the beams, columns etc. Only the primary structure is included in the model and it's my job to "fill out" the model by...

I'm trying to understand a graph in the publication "Design of Blast Resistant Buildings in Petrochemical Facilities" published by ASCE. On page 3-7 Fig 3.2a shows the relationship described in the subject of this post for a Shock Wave. I fail to understand why the reflection coefficient Cr...

Hello, I have a question concerning the capacity of L-bolts used in a slightly unconventional way. An external wall is constructed from aerated concrete panels. The panels span horizontally across columns at suitable spacing. The panels are attached to the columns by L-bolts hooking round the...
