4. mezire regilyèman midspan déplacement pou jwenn si pa gen tikal pa tikal amélioration. Gwo vitès déplacement amélioration pwal nan pwopòsyon dirèk ak degre Port tache ak pinhole yo, ak degre améliorer la pwal yon ti. Si gwo vitès déplacement amélioration twò vit, li montre ke ke gen domaj pou bwòch, pinhole, anwo ak anba bastengal corde manm (ki enkli manb corde renforcé), se pou sa, detaye enspèksyon dwe fè pou tèt li adopte mezi.

4. Measure regularly the midspan deflection for finding whether there is gradual enhancement. The speed of deflection enhancement shall be in direct proportion with the wearing degree of pin and pinhole, and the enhancing degree shall be very small. If the speed of deflection enhancement is too fast, it shows that there’s damage to pin, pinhole, upper or lower truss chord member (including reinforced chord member), therefore, detailed inspection shall be made for adopting measurement.
