Abstract:
The Fressinet method of arch construction had not been trio d in this country until it was introduced in the construction of the Rogue River brid method of strain ad’ustment was stu behavior of an arch 8 e in Oregon. This ied as well as the when it is first put under dead load. The compensating strains were produced with batteries o f hydraulic jacks placed in one or more radial joints in the arch ribs. The method is simple and effective in eliminating the deleterious effects rib shortening to its most f and permits an adjustment of the arch avorable elastic state under combined dead and live loads. The Freyssinet method permits greater economy in arch construction even in moder-ate span lengths and makes longer spans and smaller rise ratio practicable,
