This paper deals with the development of structural system for the timber-UHPC composite lightweight bridges and summarizes the results and evaluation of part of the short-term push-out shear tests of the special timber-precast concrete composite connection. Specimens for the push-out shear test are composed of two identical precast UHPC slabs and timber beam placed in the middle between them. The shear connection is carried out by notch made of steel plates embedded in the timber beams supplemented with welded headed studs. Some parameters of the shear connection are varied and their influence on the mechanical behaviour of the connection is discussed. The executed experiments are supplemented with numerical simulation and compared with analytical calculation.
