Question

The sketch below shows the section of the window to the left with steel angles holding the glass securely. Why would this not be a good window for an exterior wall?

Answer 1

This window is a angular window whigh makes a angle heff than 180° Cout side angle) s shown below. Comparitively with straight window as I Intesanal Aarea External Area External 1 - Area Disco internal fois <180° whea When ever the external window angle ise than 180° then the accumulation of the wind is more at the same time the wind pressure on the window glass is more hence there is . a possibility of breakage. 1. Here I will show the wind load des and wind pattern on the windows with the exterial a part included angle is c180 C >180°. k I is >180 o is <180° - Wind - flow more wind load Pressure Z wind flow on the window glass - wind lood pressure on the windw glass is bell S and it is distributed. If 0=180° the load (wind pressure) acts disrectly. IF 0 <1800 then load is accumulated to words center çe e 3180 then loadis distributed Ee impact is less.

Hence in the given picture is the window angle is a held than 1800 hence the wind load is more and the wind is accumulated towards the centre of the window and impact of wind flow, wind bad is more be so it is not suggestable window type It is a not be a good window for an exterior wall. More wind forces taken by the external wall only. 3 Scanned with CamScanner
