裂缝多的

Its shock waves spread through L'Aquila, shaking to the ground a hotel and several apartment blocks. They wrecked a university residence, trapping many students inside. The earthquake gashed solid 18th-century palazzi and shook the brickwork out of flimsy structures thrown up in the 1960s. Bridges and viaducts in the city, high up in the Apennine mountains that form Italy's backbone, were left perilously fractured.

震波穿过拉奎拉向四周传播，一家酒店和几个公寓住宅区被夷为平地；某大学宿舍区遭到破坏，多名学生被困其中；许多坚固的18世纪建筑出现了裂缝，多座建于20世纪60年代的建筑的脆弱墙体出现砌砖脱落；市内多座桥梁和高架桥断裂，这些桥梁曾连接亚平宁山区，是意大利的主干道。

Based on the shell element degraded from the continuous body, concrete and configured steels are modeled by the layered shell element, and the vertical steels burdened with added loads are completed by the combined shell element. Then, with the smeared crack model, associated flow rule and Madrid hardening model, the material nonlinearity of the concrete is depicted. The stiffness matrix of nonlinear thin-walled shell element is deduced. As for RC multi-T girders subjected to transverse loads, the properties, such as crack expanding and steel yielding, are studied.

With the development of the prestressed concrete construction technology, more and more prestressed concrete box girder bridges have arisen in our nation. However, after construction, the appearance of the cracks on some of these bridges takes some unfavourable influence on the structures. In common sense, we should take some methods to strengthen and repair these bridges as soon as possible, but because of the civil pecuniary condition, we cant repair all the broken bridges in one time. Therefore a scientific estimation must be made about the load-carrying capacity of these prestressed concrete box girder bridges with cracks, so that we can decide which bridge should be repaired firstly.

随着预应力施工技术的不断进步，我国已拥有越来越多预应力混凝土箱形梁桥，这些桥在使用一段时间后，有很大一部分箱梁出现了大量的裂缝，这些裂缝的出现对桥梁结构将产生不利的影响，所以应尽可能的对其进行加固修补，但限于国内实际经济状况，我们不可能一次性全部进行加固改造，需要对在役的这些开裂后的预应力梁桥的工作状态特别是承载力做出科学的评判，以便区分轻重缓急，优先实施。
