I am designing a really simple one story light frame [wood] building for a place with a Seismic design category E, when I was reading the special inspections and the requirements for masonry, there was no information that prohibited me from having veneer. Then somebody kindly pointed out Section...
Hi everybody,
I was wondering if anybody can point me in the right direction. I am designing some boxed headers and need them taking some lateral loads due to some rather large openings. The typical software we use is the Clark Dietrich's AISIWIN but it doesn't allow the user to do lateral...
NDS 3.7.1.4 states that compression members should be limited to a slenderness ratio of less than 50. Are studwalls included in this rule? Why is this generally ignored, I mean, software does warn you when you do use a member that exceeds this ratio but it's not clear on the commentary whether...
Hello fellow engineers,
I'm in a bit of a pickle. I'm designing a 4 story wood structure, very regular in shape, not so much in wall continuity. As usual, due to architectural constraints, plumbing walls and other headaches, I am not able to use most of the walls as shearwalls. So the way the...
Hiya,
I am designing a steel building with eccentrically braced frames [picture attached], the analysis was performed using RAM Structural System [my first time using it, i am a SAP/ETABs User]. The thing is that because of silly architectural requirements we are not allowed to use full frame...
Hello
I am right now programming some frame analysis software and I'm trying to implement a member design routine for the program, the thing is, I'm not really sure what procedure has been proven to be more effective. I was thinking of following an approach similar to Aminmansour's procedure...
Hello,
I am modelling a mezzanine with 5x1 25 ft bays. I am wondering whether this should in fact be or not braced. I was debating on the lateral load that should be placed per code and my coworkers argue that it should be .02*(TOTAL DEADLOAD) but I cannot find anything in the code regarding...
Hiya,
I'm writing some python code to automatize design of individual member based on loading conditions. Anyways, I haven't had the chance to do re-write the whole NDS set of tables to a spreadsheet and I would like to know if anybody has or has run into an spreadsheet that contains all the...
I am designing a wood building. Due to some construction problems we had to remove the sheathing in one of two contiguous bearing/shear walls because contractors were struggling to actually nail the sheathing. Anyways, we were having a discussion at work because somebody picked up one of my...
Hiya,
I'm designing a wood building that has some Decks that are held partly by the wood structure and partly by masonry piers. When it comes to the analysis of the Pier I don't know if I can take the length of the floor-to-floor as the effective length. In my opinion woods doesn't really...
This is sort of an odd question, what part of the code regulates the allowable min. height between floors (I'd refer to it as free height, although I'm not sure exactly how they refer to it in english). In my country we have a required min. height in residential buildings of 2.20 m meaning that...
I'm doing a vibration analysis with the AISC design guide 11 on a set of steel joists, the problem is that the manufacturer tables do not really give me the chord areas that i need to perform the analysis, are there any existing tables that have these properties or a way to calculate this as...
Anybody has any idea how to calculate the acceleration of a Composite steel deck supported by joists that at the same time are supported on CMU or Reinforced concrete walls?
It's not taken into consideration in the Design Guide examples and I don't know if assuming the wall is a deep beam would...
Hi there,
I'm trying to apply some wind loads to a model based on the ASCE-7-10 code but truth being told I don't have much experience working with the american code or windloads in particular. I read the code and there's nothing about applying the loads directly to the diaphragm, it's not...
Good day,
I've been doing some structural design of a school, I had never modeled joists before with ETABS, but it seems to have an option where you give the joists capacities and their moment of inertia.I know I can just give it a fixed value of moment of inertia and let it do its work but I...
