RESTORING FORCE CHARACTERISTICS OF PRECAST CONCRETE BEAMS POST-TENSIONED BY UNBONDED TENDONS AT WIDENED BEAM END
نویسندگان
چکیده
Modeling on restoring force characteristics of unbonded precast prestressed concrete beams with widened beam end was proposed in this paper. One model has rotational springs at both the outer general and end, another one spring a rigid zone end. Ten whose parameters are longitudinal rebar amount, size, prestressing force, etc., were constructed tested. The method captured test results good accuracy.

Precast, Pretensioned, Post-Tensioned Concrete for Bridge Decks
The problem of concrete bridge deck deterioration on many of our newer as well as older bridges is severe, somewhat perplexing as to cause, and difficult to solve. Furthermore, the cost to highway agencies for their repair, and the cost of delay to the highway user, can be extremely large. The use of precast, prestressed concrete for bridge decks is a con cept of construction or reconstruction...
متن کاملNonlinear Models of Reinforced and Post-tensioned Concrete Beams
Commercial finite element software generally includes dedicated numerical models for the nonlinear response of concrete under loading. These models usually include a smeared crack analogy to account for the relatively poor tensile strength of concrete, a plasticity algorithm to facilitate concrete crushing in compression regions and a method of specifying the amount, the distribution and the or...
متن کاملExperimental Study and Modeling of Reinforced Concrete Beams Strengthened by Post-Tensioned External Reinforcing Bars
The utilization of unbounded external reinforcing bars is one of the strengthening methods used after loading stage and before failure. The method has been used in different forms to strengthen members of reinforced concrete structures. To investigate the effect of utilization of post-tensioned reinforcing bars in this method of strengthening, a number of reinforced concrete beams was tested. S...
متن کاملUnbonded Post Tensioned Concrete in Fire: A Review of Data from Furnace Tests and Real Fires
The fire-safe design of concrete structures which incorporate post-tensioned prestressing tendons has recently been the subject of debate within the structural engineering community, particularly when unbonded post-tensioned (UPT) prestressing tendons are used. Despite several studies aimed at furthering our understanding of the response of UPT concrete structures in fire, many aspects of their...
متن کاملUltimate Tendon Stress in CFRP Strengthened Unbounded HSC Post-Tensioned Continuous I-Beams
The use of unbounded tendons is common in prestressed concrete structures and evaluation of the stress increase in unbonded tendons at ultimate flexural strength of such structure has posed a great challenge over the years. Based on the bending experiment for two-span continuous post-tension beams with unbounded tendons and externally applied CFRP sheets, the monitoring of the stress increment ...
