How to extend beam in STAAD.Pro?

In previous article we saw how to extend beam in ETABS, now let us see how to extend beam in STAAD. Following are the steps to do the same. 1. Select the beam line which you want to extend. 2. Go to geometry → Stretch selected member command. Or select the button shown in the red box which is the shortcut for stretch member command.  3. Tick on “To an existing member” and select the cursor shown against it. 4. Select the member up to which you want to extend the line. 5. Your beam line is extended to the existing member. 6. If you want to extend up to an existing node, tick on “To an existing node” and select the node to which you want the beam to be extended. 7. Enjoy STAAD.

How to Extend a line in ETABS?

Many a times we need to extend beams to the perpendicular beams some distance away. In ETABS, we have to follow a procedure to do the same. Following are the steps you need to do in order to extend a line. Select the line and the end point of the side you want to extend along with the line up to which you want to extend.      Go to Edit → Align points/lines/edges →extend line object → OK.   Line is extended.    you may also like to read How to extend beam in STAAD Pro.?

How to find the mass of reinforcing bar quickly?

Simple way to find the weight of reinforcing bar: The density of steel is 7850 kg/m³. Now let say you want weight per m. then what will be the formulation? Check this out. 7850(kg/m³) x [pi()/4 x d² ](m²)= mass of the bar per m.        (eq. 1) Now resolving this we get 7850 x pi()/4 = 6165.375 right?   Putting this into eq. 1                          6165.375 (kg/m³) x d² (m²) = mass per m.                                          (eq. 2)   What can be bar diameter? Let say 10mm, 12mm. . . we are used to mm format bar diameters, right? So, let us make formulation to eq. 2 for inputting bar dia as mm.              1m = 1000mm. => 6165.375 x 10^-6 =   1/162.196 Hence, mass per m of bar = d² (mm²)/162.196. Now if you want to get mass per feet, then use this relation 1m = 3.281 feet  Therefore mass of bar per feet = d² (mm²)/(162.196 x 3.281) = d² (mm²)/532.139. So now onwards, please don’t bother to use d²/162.2 for finding mass of reinforcement. Enjoy
