Exercise $3\mathrm{.}7$

Finally, we will examine a section view from a 'real world' structural General Arrangement drawing, and attempt to understand it$.$ The figure on the right shows a plan view for part of a building floor. A section view, $\text{'}7-7\text{'},$ is shown on the next page. This is the first time you have encountered a drawing from a real building structure $-$ it may look a little complex at first but don't panic! A list of common symbols used in these drawings is given.

You have $5$ tasks:

Insert and label the cutting plane corresponding to section $\text{'}7-7\text{'}$ in the plan view. Assume it lies at a distance $2200mm$ from gridline $02.$

Mark the location of the beams and columns on the plan view.

As drawn on the next page, the section view $\text{'}7-7\text{'}$ does not show the full width of the floor plan presented. Extend the section view to do this.

Create a section view $\text{'}8-8\text{'}$ along gridline $H,$ looking towards gridline J$.$ Mark the section in the plan view. Draw the section on the next page, below Section $\text{'}77\text{'}.$

Finally, produce an isometric sketch of the floor area shown.

Assume all columns are continuous above and below the floor plan shown.

For clarity, it may be helpful to use a different colour when marking the plan view if you can, but it's not essential.

Refer to the lecture notes for a very brief introduction to the idea of beams, columns and slabs in structural schemes.

$,$ All dimensions are in $mm$

$,$ Note $w$ stands for 'wide' and $dp$ for 'deep', so Foow $750dp$ means $700mm$ wide by $750mm$ deep beam

Finally, note that for clarity the scale on the plan view on this page and section view on the next page is not the same
