Research on shear design method for
reinforced concrete beam
Abstract: The shear capacity of reinforced concrete beam research is a classical topic in the study of basic theory of concrete structure, because  its complex failure mechanisms , affected by many factors and has attracted many attentions of scholars at home and abroad. Nearly one hundred years, researches proposed from different angles, different kinds of theoretical formula. These theoretical formulas was difficult and complex form is not convenient for engineering application. Most countries in the design formula has the empirical formula or a certain guaranteed rate of return based on the experimental data. This paper mainly has carried the following research:
1.The representative GB10, ACI318-08 and CSA A23.3 shear design formula of specification and the relevant provisions are introduced and the various specifications formula considering the influencing factors were compared. 源自L六^维:论`文~网-.加7位QQ3249`114 www.lwfree.cn
2. Select the engineering parameters similar to the actual test data 71 shear beam, the establishment of a wide range of parameters covering small shear database.
3. Based on database, the GB10 ACI318-08 and CSA A23.3 specification of shear design formula were analyzed and evaluated.
