LSD theory was implemented formally in Czech practice in 1966 but it was opposed by most professionals. The theory was contrary to the former successful Safety Factor Design and objections were targeted especially against the Ultimate Limit State Design (ULSD). The development of Eurocode (EC) 7-1 began at the end of 1970 and met with similar opposition. However, the same problem was solved in a different way with the Czech standardization which had implemented the LSD with another definition of characteristic input values. The European standardization retained the classical LSD including geotechnical ULSD although design problems were not solved satisfactorily. Now, EC 7-1 has come into force in the European Union (also in the Czech Republic) and it is in a period of calibration. The most serious problem is the ULSD application for geotechnical (non-linear) tasks using derived material inputs which appear to be very inadequate.
