%X This paper considers the global structure of positive solutions for a fourth-order boundary value problem with first derivative{u^{(4)}(t)=rf(t,u(t),u'(t)), t∈(0,1),u(0)=u'(0)=u″(1)=u(1)=0,where *r* is a positive parameter, *f:［*0*,*1*］×［*0*,∞)×［*0*,∞)→［*0*,∞)*is continuous, and *f(t,*0*,*0*)=*0*.* When the parameter *r* changes in a certain range, the global structure of positive solutions of the problem are obtained by using the Rabinowitz global bifurcation theorems. The conclusions in this paper generalize and improve the related results.
