Slope deflection method sway portal frame numerical probleam

Analysis the portal frame shown in following fig. by Slope deflection method and draw bending moment diagram.


Answer:-

Slope deflection method is help to determine the bending moment of sway portal frame.

Step 1:-  At fixed support the angle is zero i,e it and the deflection in beam as a delta is shown in fig. All loads are applied on it.





Step 2:- Very 1st the calculation of fixed end moment is determine by using simple fixed end formulas. And the sign convension are placed -ve & +ve respectively.

Types of Stairs


The stairs may be built with wood, concrete masonry or with cast iron. Wooden stairs are not safe, because of the danger of fire. However they are used in buildings to access to small areas in the upper floors.

 Cast iron or steel stairs in the spiral forms were used commonly to reduce stair case area. In many residential buildings masonry stairs are also used. Reinforced concrete stairs are very commonly used in all types of buildings.

CELLULAR CONCRETE


It is a light weight concrete produced by introducing large voids in the concrete or mortar. Its density varies from 3 kN/m3 to 8 kN/m3. It is also known as aerated, foamed concrete.

Properties of cellular concrete
1. It has low weight.

2. It has good fire resistance.

Moment Distribution Method Portal Frame Numerical

In this video i completely explained the procedure for solving the MDM of portal frame. This method is very important for analysis of any building. We can solve this method by fallowing steps:-

1_ Determination of Fixed End Moments
2_ Determination of stiffness factor
3_ Determination of Distribution factor
4_ Solving sway and non sway MDM table to get joints moments
5_ Determination of sway correction factor
6_Simple bending moments
7_Final bending moments diagram

Clapeyron's three moment theorem by parag pal Part-2

                               
This video is all about Clapeyron's three moment theorem. In this video the detail solution is given by mi that how to solve the TMT. This type of nums important to analysis the beam.

Non sway portal frame analysis by Kani's method


Kanis method is important to analysis the portal frame as well as the beam. In this method the more number of interations are important. The kanis method having sway and non-sway portal frame which comes in some little difference that is the story moment. Solve the nums by this method as I listed in video. ENJOY
