Features of the prestressed concrete strand 1.High tensile strength, low relaxation, stable modulus of elasticity, stress-relieved, straight, firm connection with concrete. 2.Unbonded and bonded prestressed steel strands have good corrosion resistance and small friction of unbonded tendons, which can be easily bent into curved shapes.
O’Reilly’s ‘Total Precast Structures’ are being used for many types of buildings including apartments, parking structures, retail developments, offices, student accommodation, custodial, and industrial buildings. Architectural and structural precast concrete
This book is concerned with the dynamic behavior of reinforced/prestressed concrete structures, such as: buildings and bridges. It discusses how to predict or check the real inelastic behavior of concrete structures subjected to dynamic loads, including equipment loads, earthquake motions, seismic interactions and missile impacts.

Our leading products are steel strands for prestressed concrete structures. These are popular for use in the construction of roads, bridges, high rise buildings, and even water conservancy projects. Stainless Steel Product Base
STRUCTURAL ENGINEERING Structural engineering (STE) has always been seen as one of the few professions where one can coine real technical skills with artistic flair. Structural engineers are known to be people who enjoy innovation, opportunities, responsibility and excitement, whilst working within a creative profession. Structural engineers plan and design various structures such as buildings,
1/3/1998· The authors conducted a series of experiments using hodic protection system on prestressed concrete structures in order to establish the reliable hodic protection systems. This article indied some experimental results on susceptibility of prestressing steel to hydrogen erittlement and mechanical behavior of pretentioned beams subjected to current supply.
Better understanding of behavior of reinforced concrete meers such as load carrying capacity-drift relation is absolutely necessary. Fiber model using FORTRAN coding was developed, in order to simulate hysteresis response and backbone curves of prestressed concrete beams with T …
The merchandise covered by this Petition is prestressed concrete steel wire strand (“PC strand”). PC strand consists of multiple steel wires (non-stainless and non-galvanized) wound together to produce a strong, flexible product used to strengthen prestressed concrete structures.
This paper discusses the applicability of precast hybrid moment-resisting frames (PHMRFs) coined with precast concrete rocking walls (PCRWs) for realising seismic resistance in buildings. The coined system was investigated through experimental and analytical studies.
Structural Concrete discusses the design and analysis of reinforced and prestressed concrete structural components and structures. Each of the eight chapters of the book tackles a specific area of concern in structural concrete. The text first deals with
