MIM $106$E Structural Mechanics Homework $($Example$)$

Choose a small one$-$story timber structure. Briefly give information about architectural aspects and geometrical details such as plan dimensions, story height, member sizes.

Figure $1.$ Timber residential building.

$2.$ Label the load bearing structural members. Illustrate the loads acting on the structural members as shown in the Figure $2.$

Select one of the roof beams and check the safety of the beam. In this example roof beam $2$ has been selected. If the cross$-$sectional dimensions of the selected beam is not given, select a cross$-$section for the beam.

Load acting on the roof can ben taken as $p=1\mathrm{.}50k\frac{N}{m^2}$

If the span length of the Beam $2$ is selected as $L=5m,$ then the load acting on the beam can be calculated as $p=1\mathrm{.}50k\frac{N}{m^2}2m=3k\frac{N}{m}.$

F$$gure $2.$ Load bear$$ng structural members and load$$ngs$.$

$3.$ Check the safety of Beam $2.$
