ab(be 0.4l during antidetonation
abe).When bar diameter in Vierendeel girder is comparatively large, or when wall thickness is less, usually can runs into the situation that anchoring section horizontal projection length is discontented with sufficient regulation and stipulation, cause the generation that breakaway connector destroys.
In current cast-in-place construction, can take to increase the reinforcement measure such as beam head or welding anchor plate to meet the demands, but increase beam head, common situation is that Vierendeel girder is connected with Core Walls Structure, elevator shaft is typically used as in Core Walls Structure, do not allow to arrange beam head, therefore this measure has significant limitation, and there are some researches prove and take anchor plate measure Double-anchor-head measure must could solve anchoring section horizontal projection length and be not less than 0.4l at reinforcing bar end
abproblem, so then can bring certain difficulty for construction, all the more so when particularly wall is thinner.
Therefore, be necessary to design a kind of syndeton to strengthen the anchored force of link position, to solve the problem.
