Vertical vibration of linac components (accelerating structures, girders and quadrupoles) in the NLC has been studied experimentally and analytically. Effects such as structural resonances and vibration caused by cooling water both in accelerating structures and quadrupoles have been considered. Experimental data has been compared with analytical predictions and simulations using ANSYS. A desig...

Reinforced concrete (RC) box girders are a common structural member for road bridges in modern construction. The hollow cross-section of a box girder is ideal in carrying eccentric loads or torques introduced by skew supports. This study employed acoustic emission (AE) monitoring on multicell RC box girder specimens subjected to laboratory-based torsion loading. Three multicell box girder speci...

The monitoring of a precast, prestressed girder bridge during fabrication and service provided the opportunity to observe temperature variations and to evaluate the accuracy of calculated strains and cambers. The use of high curing temperatures during fabrication affects the level of prestress because the strand length is fixed during the heating, the coefficients of thermal expansion of steel ...

Abstract The ways of designing and building steel girder bridges with a composite concrete deck vary much between different parts the world. A bridge system twin I‐girders or concept multiple (more than two) girders can be used. design use details secondary systems also lot. In order to give horizontal stabilization distribute loads, bracing bracings are often Although not so common, used verti...

In this paper, the Difference of Seismic Response across Different Spans (DSR) in longitudinal distribution High-Speed Railway Multi-spans Simply Supported Bridge (HSRSB) under earthquake excitation is investigated, and an evaluation method which can intuitively reflect difference seismic response proposed. A feasible way to strengthen connection stiffness between adjacent girders proposed cont...

A partial connection–prestressing (PCP) method is proposed in this paper to decrease the prestress that was transferred steel girders negative moment region of steel–concrete composite bridges. The connection achieved by application rubber-sleeved studs (RSS) prestressed concrete slab region. Since there no experimental research on PCP continuous girders, best authors’ knowledge, two were teste...
