An interior crack is under consideration to watch its propagation because of cyclic loading which is very common for aerospace, naval and civil engineering structures.
Introduction Interaction and propagation of cracks is a significant concept in the design and analysis of aerospace, naval, and civil structures.

This document explains and demonstrates the problem that currently the installment of ceiling project’s bearing reaction is non-standard, combined with the example of the civil fitness center decoration project in Jinan which shows that all the ceilings should be installed with bearing reactions.
This construction method has been applied into the civil fitness center decoration project in Jinan with all the ceilings are installed under the direction of the bearing reaction construction method, solved several quality problems such as cracking, damaging, desquamation, distortion,and so on., We satisfied the project quality that it was given by current specifications and also achieved good results in ensuring the construction quality, speeding up the construction progress and improving on economic benefits.

In 2006, United States Army Corps of Engineers (USACE) formulated and issued a 15-year BIM Roadmap[2,3].
The project mainly includes 896 engineering piles, -27m horizontal support, excavation under the surface of baseplate, and 24 drainage wells.
Fig. 3 Three-dimensional BIM model Engineering statistics.Compared with the traditional engineering statistical methods,Revit statistical function is more efficient and accurate.Regardless of a large number of modifications, it can automatically count volume, number, material, length and other statistics information.
Because of the outstanding engineering statistics function of Revit, we provided the owner with a more rational project quotation.

Time-dependent deterioration of Carbon Fiber Reinforced Polymer Affected by Climatic Factors Luoyi1,a, Peng Xinqian1,b, Quanfeng Wang1,c, Yang Yongxin2,d 1 College of Civil Engineering, Huaqiao University, Xiamen 361021, China 2 National Diagnosis and Rehabilitation of Industrial Engineering Research Center, Beijing, 100088, China a luoyi@hqu.edu.cn, b PXQ@hqu.edu.cn, c qfwang@hqu.edu.cn, d yangyongxin@tsinghua.org.cn Keywords: carbon fiber; deterioration; climatic factors; retain rate curve equation of strength Abstract.
Introduction Widely used in civil engineering strengthening and reinforcing, modern fiber reinforced polymer (FRP) exhibit relatively elevated climatic stability, but in prolonged exposure to climatic factors, their properties can change[1].The extensive use of these materials in different branches of modern civil engineering poses the problem of a complex study of atmospheric aging of FRP.
All specimens testing are completed in Huaqiao university civil engineering mechanics test center.

Vibration control analysis of high-rise cantilevered floors under pedestrian walking loads Manyi Qi 1, a, Zhiqiang Zhang 1,2,b , Fei Ma 1, c, and Aiqun Li 2,d 1 School of Civil Engineering, Southeast University, Nanjing 210096, China 2 Key Laboratory of Concrete and Prestressed Concrete Structures of the Ministry of Education.
When the master structure vibrates by walking excitation, the substructure is supposed to produce an inertial force in the direction opposite to the structure’s vibration, thus to attenuate and control the master structure’s response [1].The TMD system, as an effective device to suppress the vibration with the merits of being concise, reliable, inexpensive, is widely used in vibration control of high-rise structures and other civil engineering structures.
The general limit accelerations [6] for civil construction design are presented in Table 1.
