Reasons : firstly, sectional dimension is so little that torsional stiffness of single - beam is n ' t enough. secondly, protective layer thickness is too thin to protect concrete reinforced bar and reduce durability. lastly, each main beam is joined by cross girder and the more rigid of cross girder the more entirety of bridge
橋梁局部損壞較嚴重，主要原因是主梁截面尺寸過小、肋板過于薄弱，造成單梁抗扭剛度不足；保護層厚度不夠導致鋼筋外露引起銹蝕，降低了橋梁的耐久性；各主梁採用橫隔梁連接成整體，橫隔梁的剛度越大，橋梁的整體性越好，但調查結果顯示，實際情況中並不能達到理想的整體剛度。 -
Series of high pressure thermocouples thermalresistances and thermowells, the thermocouple take the form of spring - loaded, of which protective tube and flange are forged of special alloy, as well the thermowell are formed with bar stock drilled. more further, theconnecting between thermowell and flange can be compressed with tapered thread and the groove at the lower end of flange can be welded with argon arc. these thermocouples are usually used in high equipments of hydrogen cracking device, cracker and vaporizer etc for pressure - resistant in over 30 mpa, operating temperature from 0 up to 800
