Additional information on new materials! Long-term performance simulation program for concrete structures.
"LECCA2-Lite" is a long-term performance simulation program for concrete structures. It can quantitatively capture the time-dependent changes in deterioration phenomena due to carbonation, salt damage, or freeze-thaw damage in two dimensions. Designed with the general engineer in mind, it limits the analysis modes available in "LECCA2" to the necessary range for practical use. While maintaining the conventional simulation accuracy, it minimizes the number of input parameters, resulting in a more intuitive and user-friendly specification. Additionally, information on new materials based on recent findings has been added, making it suitable for the formulation of maintenance management plans.
