Introduction to Structural Analysis - Examples & Applications

Determine the degree of indeterminacy and stability of a continuous beam with three spans. The beam has a pin support at the left end and three roller supports. There are no internal hinges.

Calculate the ultimate factored load ($P_u$) for a structural column using the LRFD basic load combination: $1.2D + 1.6L$. The column supports a dead load of $P_D = 400\text{ kN}$ and a live load of $P_L = 250\text{ kN}$.

Determine the design wind pressure ($p$) acting on a building façade based on a simplified formula: $p = q_z \cdot G \cdot C_p$. Given the velocity pressure evaluated at height $z$ is $q_z = 1.5\text{ kPa}$, the gust effect factor is $G = 0.85$, and the external pressure coefficient is $C_p = 0.8$.

Calculate the factored load combination for Earthquake design using $1.2D + 1.0E + 0.5L$, given $D = 1000\text{ kN}$, $E = 600\text{ kN}$, and $L = 400\text{ kN}$.

Determine the degree of indeterminacy (DOI) and stability of a planar truss composed of $m=15$ members and $j=8$ joints. The truss is supported by a pin at the left end and a roller at the right end.

Determine the degree of indeterminacy of a 2D portal frame consisting of 3 members (2 columns, 1 beam) and 4 joints (2 supports, 2 beam-column connections). Both supports are fixed. There are no internal hinges.
