(the tables permit a bearing length of up to 3.5 inches, but since 1.5 is probably the worst case that you’ll encounter for joist or rafter bearing, it’s a safe value. Note that these calculations are rather conservative - based on steel with yield strength 36 ksi and the ASD - Allowable Stress Design - method. Table 9.1 in Span Tables for Joists and Rafters (Figure 5) gives a required compression value of 237 psi for a span of 16 feet and bearing length of 1.5 inches.
