2025年1月1日 · Definition: concrete cast elsewhere than its final position.- ACI Concrete Terminology. Precast concrete is reinforced concrete constructed by industrialized methods. It is characterized by dividing the building into components, which are manufactured in a precast concrete plant, and transported by special transportation equipment to the site.

Chapter 6—Guidelines for fabrication, transportation, erection, and inspection. Chapter 7—Examples of emulative precast concrete structures

1999年7月1日 · Keywords: precast concrete; prestressed concrete; shearwalls. DOI: 10.14359/700. Date: 7/1/1999. Abstract: Unbonded post-tensioned precast concrete walls are constructed by post-tensioning precast wall panels across horizontal joints using post-tensioning steel which is not bonded to the concrete.

1998年9月1日 · The analytically simulated performance of moment-resisting precast concrete frames with hybrid connections under seismic loads is evaluated. An enhanced and versatile hysteretic model was developed to represent the inelastic behavior of the hybrid precast connection region.
