The increase in population every year makes more and owners of motorized vehicles cars resulting full access to the highway, not only highway that experiences density while bridge is one factors due number pass at a certain time will be congested experience enough vibrations because load carried by different, greater held bridge, vibrates, therefore writer make an instrument using geophone sens...

Every year a large number of bridges flooding in the river just when they most need them there destroy all born. Carried out. In this study, the four fulcrum forms a semi-circular, trapezoidal, rectangular edges rounded rectangle 90 degrees at 70 degrees in Sagittarius with four different discharges depth of constant scouring around the abutment in pure water were examined. For material of flum...

Introduction: Some clinicians use a handheld screw driver instead of a torque wrench to definitively tighten abutment screws. The aim of this study was to compare the removal torque of one-piece and two-piece abutments tightened with a handheld driver and a torque control ratchet. Methods: 40 ITI implants were placed in acrylic blocks and divided into 4 groups. In groups one and two, 10 ITI one...

Scour is the erosion of bed and bank material by flowing water; scour poses a threat to bridge security by undermining piers and abutments over time. In fact, “the most common cause of bridge failures is floods with the scouring of bridge foundations being the most common cause of flood damage” (Richardson et al., 1993). While regular inspections and maintenance reduce the risk of a scourrelate...
