1. When prior girder's section is smaller or the concrete's intensity is lower, the supporting structure can be replaced by bearing spandrel which is added to the girder's sides. 当原梁截面较小或混凝土强度较低时，张拉预应力的支承结构可由梁两侧增设的承压钢梁充当。
2. Large-span prestressed concrete grillage girder frame structures have proved to be the effective application of the prestressing technology to the grillage girder frame structure. 大跨预应力井式梁框架结构是由现代预应力技术和井式梁框架结构结合而成的一种新型结构体系，它可满足现代建筑的大空间使用功能要求。
3. A kind of establishment method of geometric models for prestressed concrete continuous girder bridge is given, and builds the box-girder constructional geometric models. 针对预应力混凝土连续梁桥，提出了一种几何模型的建立方法；建立了箱形梁构造的几何模型。
4. Boiler steel structure consists of roof, column, girder, vertical and lateral supporting, while roof comprising of girder, secondary beam, trabecula and forming a firm box. 锅炉钢结构由顶板，柱和梁，垂直支撑，水平支撑等部件组成，顶板由主梁，次梁和小梁组成一个坚固的梁格，其四周有水平支撑，主梁端有垂直支撑。
5. The results show that the failure mechanism of SRC girder transfer floor is better than that of RC girder transfer floor. 结果表明，SRC梁式托柱转换层结构的破坏机制优于RC梁式托柱转换层结构。
