A key characteristic of SiRAC was its automation of the risk assessment process. The software would guide the user through selecting parameters for a single-zone building. Because it used pre-defined parameters that the user could not change, some values remained fixed in the program. To use the software, an engineer would input:
Simplified IEC Risk Assessment Calculator (SIRAC) was a software tool originally proposed in Annex J of the IEC 62305-2 simplified iec risk assessment calculator sirac
The primary goal of SIRAC is to determine if the risk of lightning damage to a structure exceeds the "tolerable risk" ( RTcap R sub cap T ) defined by international safety standards. A key characteristic of SiRAC was its automation
SIRAC helps simplify the calculation of these risks by managing the complex variables—such as the probability of damage, the cost of losses, and the effectiveness of protective measures 1.2.1. Key Features of the SIRAC Tool To use the software, an engineer would input:
A robust SIRAC feature should focus on automating the comparison between and Tolerable Risk ( RTcap R sub cap T ) . 1. Structure Parameter Input
) value is assigned by national authorities. SIRAC calculates the actual risk (
The Simplified IEC Risk Assessment Calculator (SIRAC) is a specialized software tool designed to evaluate the risk of lightning strikes to structures. It automates the mathematical frameworks established by the standard (Risk Management).
