A project, that's fun, educational, cool-looking and actually useful! What more could you want? We're making topology-optimized floating shelf brackets today...
Hi, I'm a Civil Engineering student doing my final project for my BE degree. I have developed a software that uses a genetic algorithm for optimizing reinforced concrete columns. I have tested my program with a 17 stories building, and got some very unusual results in the design but much...
Hiya,
I'm been calculating stress and deflection in rectangle steel plate, I've been using two methods to see if I get the same results but i get different results. I want to confirm the methods I'm using and if I'm using them correctly. I have attached photos of my calculations, any...
1. Homework Statement
In this example , the author said that we can choose either G or E as redundant and ignore the force when we are doing the analysis ...
I was told by my lecturer that when we are choosing the redundant forces , it''s important that after removing the redundant force , the...
Hello, My name is Molly Brown and I need help with basic beam and Structural Calculations. I'm not in college I just want to do this for my own satisfaction and desire to be able to understand this. Any and all help would be greatly appreciated.
I have recently finished my junior year in high school. I am seriously considering astrophysics, nuclear engineering, and structural engineering. I would love to get a degree in all of them if possible but,
which one should i get first to help me get a job to afford to get the others?
what about...
Hello all,
Our project needs to implement a force (strain) gage underwater for one of our tests. Our budget is pretty tight and we can't afford a wash-down strain gage that can support the forces that we will be operating at (~500 lbs).
Does anybody know a way to hermetically seal a strain...
Hello everyone,
I am civil engineering student from India. Im done with my undergrad with a cgpa of 8.5/10 and applied for colleges in America. I will be attending University of Texas at San Antonio for fall 2015. Im confused on which specialization that i need to opt for my graduation. They...
Hello I am looking for help with the following:
I am designing a piece of furniture where most of the person's weight will be taken on a metal (steel) rod resting on a wooden batten. I need to calculate the diameter of rod needed to ensure it is safe to sit on. As a chemical engineer I have...
I have a 300 mm diameter hole in the ground surrounded by concrete. This hole will be covered by a steel plate. I need to get a machine of weight 2.5 tonnes across this hole safely without any bending of the steel plate.
How would i calculate the required thickness of the plate?
Thank you
Ron.

Hello. I've created a small program to find shear and bending diagrams of the members of a frame. I was able to get the reactions at the support but don't know how to continue from now. This is an example of a frame all columns are 3m in height and the beams 8m. All the...
Hello.
I have a project for next semester and I'm thinking of creating a program using mathematica to analyze a concrete frame to obtain the moment and shear diagram. What would you consider the best method for analysis. The loads will be uniformly distributed.
Any tip will be greatly...
Hi,
I am designing a concrete roof slab that span across 12m long and 9m width for my living area. The support columns are placed in each 4 corners and they are 300mm x 300mm size. The concrete slab roof is cantilevered out by 1.8m on 3 sides (not all 4 sides) with the thickness of 150mm.
At the...
Hi,
I am designing a beam to replace a load bearing wall.
I have produced 2 separate UDL diagrams which, one for floor load and one for wall load. I am trying to find shear force and bending moment as in one for the total of the two diagrams. I know how to do it if the loads are spread...
I need help calculating the size of the wood members I need in my truss. I understand the basics; I first need to calculate the load, then the stress on each member, then pick a wooden member which has that stress with a safety factor of let's say 2.0. The reason why I want to perform the...
What is the difference between the unit dead load and the unit weight of a material?
For example, the unit weight for structural concrete is 145lb/ft^3. What would the unit dead load be? 145lb?
