As pioneers of urban planning practice, the city executives and technical experts of Shantou set a goal to build the city into a "perfect region" and "Garden City," aiming to create a precedent for "civil city development." Based on institutional construction and the introduction of European and American urban planning theories and experience, the rebirth of Shantou City with business characteristics had been gradually achieved by modifying and improving its city plans.展开更多

Then, the comparison on calculation methods of bending behavior including the original Chinese calculation method, the present Chinese calculation method, the present American calculation method and the present European calculation method is studied. The results show that the original Chinese calculation method of bending behavior is based on the allowable stress calculation method, and the design safety factors are 3.55 to 4. 0. In term of the calculation area of longitudinal rebars of reinforced concrete beams, without considering earthquake action, the original Chinese structural calculation method is safer than the present Chinese structural calculation method, the present European structural calculation method, and the present American structural calculation method. The results can provide support for the structural safety assessments of modem Chinese reinforced concrete buildings.展开更多
