Structural Analyses This problem has to be solved using reference method $[$the portal frames by the Moment Distribution method and the girders by the Slope$-$deflection method. And provide me full math solution step by Step.

Problem Definition

Geometry of horizontal beams:

Three spans $=I_1,I_2,I_3,$

Cantilevered parts $=I_4$

$EI=24000k.f{t}^2$

Problem Definition

The figure in the previous slide shows the arrangement of portal frames and deck girders for the elevated part of a flyover.

The objective is to analyze the portal frames by the Moment Distribution method and the girders by the Slope$-$deflection method.

The portal frames should be considered as side$-$sway frames that may horizontally move.

The forces on the portal frame include a uniformly distributed load on the horizontal member $(w_1)$ and a lateral force $(P_1)$ at the left end.

The forces on the girders include a uniformly distributed load $(w_2).$
