By the vibration tests , the dynamic property before and after the damage obtained in statics tests is tested and analyzed 通过hrb400级钢筋的模态试验,分析了此类钢筋受弯梁的模态特性,比较了无损伤梁于正常使用状态下的梁的模态特性。
In the paper , the study of analysis method of internal force for curved - beam bridge structure analyzed by spacial method of curved - bar grillage finite element method is introduced 本文对弯梁桥采用曲杆梁格有限元法进行空间结构分析时的内力计算方法进行了研究。
According to test of 4 beams reinforced with hrb400 steel bars , the question are analyzed on the flexural strength of members with different ratio , and on the crack and deflection under the state of serviceability 通过hrb400钢筋作受力主筋的4根受弯梁的试验研究,着重分析了在不同配筋率下构件的受弯承载力及正常使用下裂缝与挠度问题。
The result appears that the strength , hardness and ductility of corroded rc beam decrease with corrosion ratio , and the structure failure mode may change from flexural failure to shear failure when stirrup ratio is low 研究表明,锈蚀受弯梁的强度、刚度和延性随着锈蚀率的增加而减少。对配箍率较小的锈蚀梁,其破坏形态可能从受弯破坏转变为受剪破坏。
Moreover , it adopts modularization structure and clear flow . some numerical results form this pa per compared with these from sap93 to not only reflect correctly characteristic of curved girder but also be proved its reliability 用cbsa对弯梁桥算例进行分析并与sap93程序计算结果相比较,结果正确反映了弯梁桥的受力特性,并验证了cbsa计算程序及空间曲梁单元法的可靠性。
