Results: Before the fixed bridge was applied, under vertical load, the high-stress region was near around the apical of periodontal ligament with mainly compressive stresses. Under oblique load, the high-stress region was near around the cervical of periodontal ligament with both tensile and compressive stresses. After the fixed prosthodontics, stress and strain distributions were similar with that when the fixed bridge was not applied. But the maximum stress, strain and displacement increased apparently. The stresses in exterior surface of periodontal ligament were larger than that of interior surface; this character of periodontal ligament under vertical load was more obvious than that under oblique load.
结果:固定桥修复前,垂直载荷下,基牙牙周膜的应力以压应力为主,应力集中在根尖;斜向载荷下,基牙牙周膜的应力主要是拉应力和压应力,应力集中在唇、舌颈缘;固定桥修复后,基牙牙周膜的应力和应变分布规律与修复前相似,但最大应力、应变值都明显增大;牙周膜内表面的应力大于牙周膜外表面;垂直载荷时,牙周膜内、外表面的应力差异更为显著。

Such parameters as the percentage of ordinary reinforcment, amounts and configuration of unbonded prestressed tendons, the ratio of span to depth and the loading patterns were considered. Based on the results, the fomula for the eqivalent length of deformation zone on the beams at ultimate were developed. A simple formula was developed for the ultimate mid-span deflection of concrete beams with concept of equivalent length of deformation zone, and the deformation of beam before internal reinforcement yielding was predicted by the traditional formula for the deformation of partically prestressed concrete beam. Then an analytical model was deduced for analyzing the ultimate stress increment in those concrete beams prestressed with external or internal unbonded tendons based on the mid-span deflection.(4) Testes were carried out on a thin-walled concrete box beam presressed with external CFRP tendons to study its short-term performances under uniform load, long-term behaviors under uniform load, and full-time performance under four-point load in turn.
