Dear Sefians,

Could you comment on the behavior of attached composite beam.
You may imagine a laterally loaded solid shear wall to relate the problem to a real case.

1. Will the behavior of given composite beam ( for case 1 and case 2) will be different as compared to a solid section beam ( (Euler-Bernoulli or Deep beam) with same concrete cross-section area.


2. Will it make difference if I remove all the connectors or I provide too many connectors (two extremes).

Please find attached diagram.

My understanding says that it should not make any difference as in-section analysis no variation of strain across width (forget shear lag for time being). Even if no connector, strain variation across depth will be same, just add up capacities for two parts. Only difference might have been if width/depth was a governing parameter, which is not the case here.

There may be different scenario for  hysteresis curve and energy absorption characteristics in case of cyclic loading.

Is my understanding right?

With Thanks & Regards
