: Analysis of high-tensile steel, concrete strength, and time-dependent properties like creep and shrinkage.
: Over-exploiting compressive stress limits can lead to an excessive number of strands, making actual construction difficult and prone to error. : Analysis of high-tensile steel, concrete strength, and
: He pioneered the system where a bridge is fabricated at an abutment and "pushed" by hydraulic jacks across a valley, which was particularly useful in harsh European climates. : Analysis of high-tensile steel
