Precast-Prestressed Concrete PilesEpoxy DowelPile SpliceGFRP DowelGlass Fiber Reinforced PolymerSplice DesignFor various reasons including shipping and operation limitations and unforeseen soil conditions, it often happens that splicing of precast-prestressed concrete pile (PPCP) segments has to be performed ...
3.In view of the deficiency of load-bearing capacity evaluation method of existing prestressed concrete hollow slab,load-bearing capacity evaluation method was represented,inspection index was presented,and inspection content,method and result were introduced based on the example.针对目前既有预应力混凝土空...
Precast concrete offers a solution, because of the advantages of high quality factory made units, speed construction, and the reduction of site formwork and labor. This research consisted of several thesis titles that were grouped based on structural elements with the two systems infilled and open...
A precast concrete storm water vault comprised of modular precast concrete components is provided. More specifically, a vault is provided that consists of a perimeter of footings with integral vertical walls extending therefrom that supports precast concrete roof panels that comprise the top horizontal ...
The pile caps are completed with a final cast-in-place concrete infill, which makes the precast shell composite in the final foundation. A key design challenge was limiting temporary cracks and reinforcement stresses in the thin shell elements, by ensuring ultimate and service criteria are met ...
The paper introduces the work process and control requirements of precast concrete pipe pile perfusion. Th design is based on the S7-200PLC and AE80THTD touch screen control system. It elaborates the hardware components of control system, I/O configuration, software workflow and control chart. ...
Design And Construction Of Pile Foundations - Code Of Practice - Part 1: Concrete Piles - Section 3: Driven Precast Concrete PilesBureau of Indian Standard
The test results confirmed that the proposed design method meets the safety and performance requirements of the codes under seismic loadings. The pins maintained structural integrity with minimal damage, while the columns reached the full plastic hinge capacity. The analytical studies consisted of (a)...
The manuscript investigated the influence of the design parameters of precast pipe piles on the soft ground treatment in the Jianghan Plain based on the case of the soft soil subgrade project of the Xiaogan south section of the Wuhan city ring expressway, China. Midas GTS NX 2019 finite ...
