optimal designdigital simulationA bidirectional ribbed concrete beam slab structure was widly adopted for the upper space of industrial buildings.To maintain ample space and minimize the presence of conventional columns,a bidirectional prestressed concrete beam is often employed.The intersec...
Prestressed concrete beam bridge cross-section using T-shaped cross-section. Anti-shrinkage reinforcement requirements adopted under the dense arrangement of all the memorial steel welds are double-sided welding, using a special form of prestressed reinforcement arranged in assembly is completed, tension ...

This paper presents the complete test results of a prestressed concrete (PC) beam, including the hydration temperature of the hardening process, the behavior of the PC beam under sustained loading and assessment of damage, such as the locations of cracks and their corresponding depth. Hydration tem...
Design of Prestressed Concrete Beams with Tables for the Determination of Beam Cross Sections THE DESIGN IS DISCUSSED OF PARTIALLY PRESTRESSED CONCRETE BEAMS, COVERING ALSO THE TWO LIMITING CASES, I.E., FULLY PRESTRESSED AND ORDINARY REINFORCED CONC... W Connolly - Dodge 被引量: 6发表: 1960年 ...
reduction in ductility; increasing the tendon eccentricity has the effect to increase both the stiffness and strength of the beam; the increase in reinforcement area in the slab slightly increases the stiffness and strength; and increasing the concrete strength slightly influenced the elevation of the...
“The Big Beam competition is an outstanding opportunity to introduce the next generation of designers to precast, prestressed concrete design and construction,” said PCI President and CEO Bob Risser. “By working with PCI member producers, the students get a hands-on educational experience as well...
Numerical Analysis and Photoelastic Experiment for the Joint Structure in the Rigid Frame Bridge with Continuous Beam刚构连续梁桥墩梁固节点结构的光弹性试验... The main portion of a railway super bridge is a prestressed concrete rigid frame bridge with continuous beam. The total length of three-spa...
·m,their error is appreciably big because of the idealization of the model.Analysis result shows that the nonlinear variations of all variables for prestressed reinforced concrete beam may are simulated by using finite element method in loading process as a whole,and the solution of ultimate ...
The U-shaped prestressed concrete continuous beam bridge has the advantages of low building height, sound insulation, noise reduction, good safety guard performance, shortened bridge length and the like, and can effectively lower the construction cost of the bridge and the total construction cost of...
