(Figure 15.4). The British Standard specifies higher positive (downwards) net pressure
coefficients than negative values for local cladding loads, along the edges. ASCE-7
specifies higher local pressures than any other document.
Case (c)—Square plan enclosed building with arched roof
Figure 15.5 shows the pressure coefficients for an enclosed building with an arched roof,
which is covered in all codes except the British Standard. The ISO Standard only
