On pg 13 of 14 the weights are taken as 30% for Dead and 70% for live. Please explain how you arrived at these weights
Karthika,
As you have mentioned, the alpha conversion factor will be based on the load combination factor and the weighted contribution of the load types based on the individual project. The example that you are seeing in Table 7 on page 13 / 16, is for illustrative purposes only, to show how to calculate the alpha conversion factor. Ultimately, it will be up to the engineer of record to provide the weighted load average, and confirm the use of the correct load combination equation to determine alpha. For your reference, attached is a copy of the ICC-ES Technical Letter describing this subject in more depth.
Let us know if you have any additional questions.
Regards,
Bryan
