The smart Trick of Bridge Bearing Replacement Provisions That Nobody is Discussing


<h1 style="clear:both" id="content-section-0">The Facts About Bridge Bearings - California Department of Transportation Uncovered<br><img width="302" src="https://www.hydraulicmoldingpress.com/photo/pl18441018-fully_automatic_400_ton_hydraulic_press_machine_four_column_hydraulic_press.jpg"><br></h1>

<p class="p__0">The primary girder cast in C55 concrete is n-shaped in cross section. The width of the primary girder is 27. 5 m. Poyanghu Bridge was constructed and opened to traffic in 2000. Nevertheless, in July, 2019, its administrative personnel identified damages in both the downstream side and the upstream side bearings set up on top of the auxiliary piers.</p>
<br>
<p class="p__1">Their tensile capability is 3300 KN, and compressive capacity is 4200 KN. Keep Checking Back Here of the broken bearings is 150 cm 112 cm. The rotation angle limitation is 0. 02 rad, and the longitudinal and the transverse displacement limits are 15 cm and 2 cm, respectively, for the bearings. The cross-section view of a bearing is displayed in Figure 3.</p>

<br>
<p class="p__2">Besides, transverse displacement was observed for the primary girder near the downstream side bearing. For the upstream side bearing, two anchoring bolts broke (Figure 4(b)). Based upon engineering experiences, the administrative personnel thought that the mechanical state of Poyanghu Bridge threatened at that time. If the bearings were not repaired in time, the security and the serviceability of the whole bridge may be endangered.</p>

<br>
<p class="p__3">They are reported as follows. Repair work scheme 1 is a two-level repair plan, which depends on the tensioning of the steel strands. The first level of repair is an emergency rescue practice, which uses the four X-shaped steel strands set up near the bearings tensioned with 1000 k, N force each to quickly enhance the stability of the structure (Figure 5(a)).</p>

<p class="p__4">6 meter long steel channel members with the measurement revealed in Figures 5(b) and 5(c) set up on two sides of the bridge piers by planting reinforcing bars at the height of 1 meter listed below the capping beam. Therefore, the repair practice might trigger the damage of the piers at the connections of X-shaped steels.</p>
<br>
<p class="p__5">Their random sample location is 16. 69 cm2; their weight per unit length is 13. 1 kg/m; their external size is 6. 1 cm; their breaking force is 2620 k, N; and their strength is 1570 Mpa. The 2nd level of repair work is a repair practice in its real sense, which uses eight vertical steel strands tensioned with 2000 k, N force each to position correctly the main girder in relation to the bearings to facilitate the repair of the bearings (Figures 5(d) and 5(e)).</p>
