Which Modification Factors used in calculating the design capacity of timber elements accounts for environmental issues affecting the strength of members?
Expert Solution
Step 1 Modification Factors
Modification factors are the factors that are used to change the characteristics of material by enhancing its properties to make it more reliable and efficient.
For designing timber elements we need following modification factors ;
1. K1 = Duration of load
2. K2 = Load sharing factor
3. K3 = Shape factor
4. K4 = Depth factor
5. K5 = Thermal factor (purely based on environmental conditions)
