![]() ![]() ![]() NOTE: Long-term concrete modulus = Age-adjusted concrete modulus Ec(t,to), given as:įor example, assume that 25% of the LIVE load is sustained. Creep and shrinkage are included only in this sustained portion of analysis because these effects are only applicable under sustained loading. Sustained portion, in which long-term cracked analysis considers the sustained loading from DEAD, SDEAD, and a portion of the LIVE load. Non-sustained portion, in which cracked-section analysis considers only the non-sustained portion of LIVE load, solving for incremental deflection.Long-term cracked deflection, in which analysis is divided into the following two categories: Immediate cracked deflection, in which all loads (DEAD + SDEAD + LIVE) are applied in a single load pattern, then analysis is run with the Crack Analysis option. All load patterns are applied in a single load case which uses either immediate or long-term cracked deflection, discussed as follows:.Long-term cracked deflection accounting for creep and shrinkageĬracked-section analysis is run in SAFE using either of the following two methods:.How are cracked sections analyzed in SAFE?Īnswer: Two types of cracked-section analysis are available, including: ![]()
