【提要】  錨栓在提高板柱連接的強度和延性方面具有優(yōu)良的性能。為了考察錨栓的抗沖切性能,進行了三個配置錨栓和傳統(tǒng)箍筋的板沖切對比試驗。試驗表明錨栓比箍筋更能有效地提高板的抗沖切能力和改善板柱連接的延性。根據(jù)國內(nèi)外試驗資料,探討并提出了抗沖切錨栓的設(shè)計構(gòu)
造措施,同時結(jié)合我國現(xiàn)行《混凝土結(jié)構(gòu)設(shè)計規(guī)范》(GB50010—2002)提出了配置錨栓的板抗沖切設(shè)計方法。所提出的公式的計算值與試驗結(jié)果符合較好,并具有一定的安全度,可供采用錨栓進行抗沖切設(shè)計時參考。

Design of Studshear Reinforcement for RC Slabs/Liu Wenting,Huang Chengkui(State Key Lab. of Coastal & Offshore Engin., Dalian University of Technology,Dalian 116024, China)
Abstract:Three specimens for slabcolumn connections with stirrup and studshear reinforcement are tested.Test results reveal that studshear reinforcement is more efficient than stirrups in increasing strength and ductility of slab.Based on the tests presented earlier domestically and abroad,rules to design and detail studshear reinforcement in accordance with China Code GB50010—2002 are presented.
