Research on Mechanical Properties and Engineering Application of Modern Timber Structure

Modem timber structure holds many virtues in the fields of construction, such as energy-saving, green, aesthetics, etc, superior to concrete and steel bridge. Meanwhile, it is the mechanical properties of timber structure that have been attracted much attention compared with other structures. It is that glue laminated timber(glulam) satisfies high load-bearing capacity and long-span requirements of modem timber bridge. As the essential parts of elements used as columns, trusses in modem timber structure, glulam column had more full hysteretic curve with high energy-consuming ability and good seismic performance under reciprocating load was showed in this paper, and the compression strength perpendicular to grain of glulam was also studied. Finally, an engineering application was introduced. Filling the domestic gaps in bridge construction successfully, the first modem timber bridge in China has remarkable significant and greatly boosts the development of timber work.
