CNS 560於2018年版新增訂SD 550W之高強度耐震構材用可銲鋼筋,此有助於提升鋼筋混凝土構件之強度,或減少鋼筋用量以改善鋼筋壅塞所造成不利的施工品質,而現行國內混凝土設計規範之耐震設計規定仍不允許使用。本文之目的在提出採用SD 550W之梁主筋於內柱梁柱接頭內符合耐震需求的直線握裹長度,與相關設計細節。所提出之是以採用竹節鋼筋在反覆載重作用下直線握裹模型(廖柏州)為基礎。
本試驗共進行八組實尺寸RC內部梁柱接頭試體進行反覆載重試驗,本次採用梁主筋為SD 420W、SD 550W及SD 600W,研究變數包括柱深(梁主筋之握裹長度)、梁主筋壓力鋼筋發揮比例(值)、混凝土強度、鋼筋形式及擴頭於交會區之配置,以了解各項因子對握裹行為表現之影響。本次試驗結果顯示,採用SD 420W與SD 550W竹節鋼筋作為梁主筋之六組試體,由試體破壞模式與試體握裹勁度可以看出以梁極限狀態下預估之梁主筋壓力鋼筋發揮比例(值)代入廖柏州建議之直線握裹模型所得到之握裹容量進行設計的三組試體(JI4、JI5及JI6),表現之耐震行為比以ACI 318建議之直線握裹長度進行設計的三組試體(JI1、JI2及JI3)來得更好;採用SD 600W螺紋節鋼筋作為梁主筋之兩組試體,由試體破壞模式與強度折減率可以看出梁主筋採用擴頭旋入錨定之試體JI8表現之耐震行為來得更好。因此,在有效的預估梁主筋壓力鋼筋發揮比例與有效的錨定細節,所提供之握裹容量才能使內部梁柱接頭構件滿足嚴峻之握裹需求,使梁構件有效發揮撓曲塑鉸,消散地震橫力之能量。
CNS 560 has added SD 550W high-strength anti-vibration members with weldable steel bars in the 2018 edition, which helps to increase the strength of reinforced concrete members or reduce the amount of steel bars to improve the unfavorable construction quality caused by reinforced concrete. The seismic design rules for concrete design codes are still not allowed. The purpose of this paper is to propose a linear grip length that meets the seismic requirements of the main ribs of the SD 550W in the inner column beam-column joints, and related design details. The proposed method is based on the straight-line gripping model (Liao Baizhou) under the effect of the reverse load.
In this test, a total of eight sets of real-size RC internal beam-column joint specimens were subjected to repeated load tests. The main tendons of the beam were SD 420W, SD 550W and SD 600W. The research variables included the column depth (the length of the main ribs of the beam) and the beam. The main rib pressure steel is proportional (depreciation), concrete strength, steel form and expansion configuration in the intersection area to understand the influence of various factors on the behavior of the wrap. The results of this test show that the SD 420W and SD 550W bamboo steel bars are used as the six groups of the main ribs of the beam. From the failure mode of the test body and the stiffness of the test body, it can be seen that the beam main rib pressure bar is estimated under the limit state of the beam. Three sets of specimens (JI4, JI5, and JI6) designed to fit the grip capacity obtained by the linear grip model recommended by Liao Baizhou, and the performance of the shock resistance is better than the straight grip length recommended by ACI 318. The three sets of test specimens (JI1, JI2 and JI3) were designed to be better. The SD 600W threaded steel bars were used as the two main specimens of the main beam of the beam. From the failure mode and strength reduction rate of the test body, it can be seen that the main reinforcement of the beam is expanded. It is better to screw in the anchored test body JI8 to exhibit the seismic behavior. Therefore, in the effective estimation of the beam main reinforcement pressure steel proportion and effective anchoring details, the provided grip capacity can make the internal beam-colum joint components meet the severe grip requirements, so that the beam members can effectively flex the plastic hinges. Dissipate the energy of the horizontal force of the earthquake.
