H —C—C—C—C— Behavior of precast, prestressed concrete ...

This paper describes the behavior of six full-scale precast, prestressed concrete sandwich wall panels. The panels were composed of two outer precast, prestressed concrete wythes and an internal layer of insulation with shear grid reinforcement placed through the core into each concrete wythe.

L-c (1 b) where a is the shear span of the pile (distance from pile cap to assumed point of zero moment) and f3 is the concrete stress block factor defined in ACT 3 19-99,Section l0.2.7.3. It is suggested that the shear span be increased by an amount equal to the concrete cover, c, to account for possi ble spalling of the soffit of the pile cap

Behavior of Precast Prestressed Concrete Segmental Beams M. Al-Sherrawi IntroductionA segmental beam can broadly be defined as that beam which consists of a number of small segments fabricated either in their final position or in some other location, and then assembled to form the beam.Two methods are commonly used in segmental construction, depending on the particular application.

Behavior of precast prestressed concrete bridge girders ...

Abstract The instability of precast prestressed concrete bridge girders during construction have been of particular concern to bridge engineers. After they are installed on bearing supports, prestressed concrete girders are immediately subjected to environmental thermal loads that may be exacerbated by fabrication and construction errors. Thus, in this research, the environmental thermal loads ...

This investigation studied the capacity of square pile-to-pile cap connections where the precast-prestressed pile is simply embedded in the cast-in-place pile cap. Both experimental and analytical results are presented. It is shown that the plain embedment can develop the flexural capacity of the pile without distress to the pile cap of connection region provided that a sufficient embedment ...

The purpose of this study is to establish and examine the analytical methods based on FEA to predict the behavior of the precast prestressed concrete panels under blast loading. The precast prestressed concrete structures are on the rise, but there is little research in this regard explosion. In this paper, we set the variable to the three models. TNT 500 kg was an explosion in the standoff ...

This paper represents the second part of a multiphase experimental program undertaken at the University of Manitoba to study the cyclic behavior of prestressed connections for precast concrete shear walls. The first part of the study dealt with the behavior of mild steel connections. In this paper, the results of testing five full-scale prestressed connections subjected to reversed cyclic ...

The behavior, ultimate load-carrying capacity, and mode of failure of both the slender and compact L-shaped precast, prestressed concrete spandrels are presented. For loading values near the ultimate, the out-of-plane bending behavior of compact, L-shaped, precast, prestressed concrete spandrels is strongly influenced by the web-reinforcement configuration. Results from the analysis show that ...
