中華民國結構工程技師公會全國聯合會提出之「鋼筋混凝土結構標準圖」[1]不建議梁構材於距柱面兩倍梁深(2h)範圍內作橫向穿孔，此範圍一般認定是塑鉸區，依土木401-110規範第18.3.4節規定，在兩倍梁深(2h)範圍內須提供閉合肋筋以及耐震彎鉤等嚴格的配置要求，確保梁構材能有良好的圍束，其目的是確保梁構材受反覆載重時，能夠維持抗彎矩強度且無剪力破壞之風險。
周玠慈[7]研究團隊在2021年測試了總計九座試體，提供了塑鉸區以及非塑鉸區的穿孔梁補強新工法，並提出一套強度評估建議計算式，惟九座試體的試驗結果皆為撓剪破壞而非剪力破壞，故難以驗證不同補強方式下真實提供的穿孔剪力強度，亦難以依其結果修正強度評估建議計算式。
本研究共進行五組反覆載重下之懸臂穿孔梁試驗，穿孔位置為一倍梁深之外，以穿孔補強筋型式以及補強筋尺寸為參數，穿孔補強筋包含雙方型一筆箍以及增加穿孔兩旁之補強肋筋進行搭配，期望藉由剪力破壞探討不同補強筋搭配下之穿孔剪力強度，並藉由剪力破壞時之真實抗剪強度，訂定混凝土壓桿強度修正係數"λ" _"c" ，調整強度評估建議計算式，同時比較日本建築學會‧鋼筋混凝土建築物之韌性保證型耐震設計指針（1999）[3]及日本建築學會‧鋼筋混凝土構造計算準則2010[4]及Mansur與Tan[5]之研究提出對於穿孔梁構件之剪力強度計算方式，來比較現有的剪力強度計算式與強度評估建議計算式，於不同穿孔補強配置下的保守程度差異。

According to the specifications of an RC beam member with a transverse opening in CSSE (2011) [1], a transverse opening in beam members should be placed outside twice the depth of the beam from the column face. This range is generally defined as the plastic hinge region. According to Section 18.3.4 of RC 401-110 , within the range of twice the beam depth, closed stirrups and seismic hooks must be provided, adhering to strict configuration requirements. This ensures proper confinement of the beam members and aims to maintain the flexural strength of the beam without the risk of shear failure under cyclic lateral load.
In 2021, the research team led by Jie-ci Zhou[7] conducted nine specimens and proposed a set of design guidelines and novel reinforcement methods for perforated beams in both plastic hinge and non-plastic hinge regions. They also proposed a calculation for perforated shear strength. However, all specimens were classified as flexural-shear failure mode instead of the shear failure mode, making it difficult to verify the actual perforated shear strength under different reinforcement methods.
This study examines the mechanical behavior of five cantilever perforated specimens subjected to cyclic loading, having an opening outside one beam depth from the support. The type and size of reinforcement are the parameters in the design of the specimens, involving double-square hoops and stirrups. The aim was to investigate the actual shear strength and to adjust the calculation for perforated shear strength by concrete strut strength modification factor "λ" _"c" , and also compared the conservatism of shear strength calculation in AIJ-1999[4], AIJ-2010 [5]and Mansur and Tan[6].
