Abstract
<p>A hybrid beam, consisting of a precast prestressed concrete (PCaPC) beam reinforced with glulam timber, has been proposed. Wood screws half driven into glulam timber were embedded into concrete beam, and its timber and concrete were connected with the screws as shear connection. A full-scale bending test of two beams with openings for equipment, such as ducts, were conducted, and it was confirmed that initial stiffness increased by 16-20% and ultimate bending strength increased by 45-57% against those calculated as PCaPC beam. On the basis of test results, a calculation method to estimate moment-deflection curve was proposed.</p>
