Abstract: High-rise building construction demands precise planning prior to actual operation. High-rise building construction has widely been planned in urban area. Curtain wall operation is one of important and fundamental operations in high-rise building construction. Curtain wall operation is composed of various activities. Precise planning is required for the effective management of such operation. Construction simulation technique has been considered an appropriate methodology for estimating construction performance which is required for the effective management of the project. However, simulation technique revealed serious limitations. Simulation technique has difficulty in preliminary modeling and application of changed conditions. This paper suggests a preliminary study for the research that overcomes traditional simulation technique limitations focusing on curtain wall operations.

Abstract: Through FEM and modal testing analysis on telescopic arm of TAMROCK1000 rock drill，attained the order natural frequency and vibration mode of the initial of the model in two different operating conditions，and make analysis of every mode of vibration，and which provides valuable reference for the optimized designs later of the machine.

Abstract: Foundations are vital of constructing pagoda. First dig the foundations, and then tram trinity mixture fills one layer after layer. In order to reinforce foundations, wooden pillars and brocken stones are used, especially in softer soil zone. In addition, there is a minority of rock foundations, mainly in the south of the Yangtze River of China. Many ancient pagodas stand up to now closely related to solid foundations.

Abstract: To meet the requirements of urban residential parking, a kind of small mechanical lifting and transferring solid garage which has three storey with a pit has been designed instead of solid garage building. The design principle and methods of the mechanical solid garage are presented.

Abstract: The Mou Estate in Qixia City, Shandong Province is listed as an important heritage site under state protection. In view of its cluttered environment and dilapidated buildings, the renovation plan puts forward three protection strategies: preserving traditional mode of production and way of life, protecting the village's overall environment and utilizing local building materials for renovation, with old materials particularly preferred. Thus mass demolition and total reconstruction can be avoided. Historical development, spatial makeup, mode of production and way of life can be preserved and heritage protection and cultural tourism can be achieved at the same time.

Abstract: Linear intersection is a frequently encountered issue in surveying engineering. The paper firstly reviews the common analytical approaches, and then introduces a new analytical approach based on Sylvester resultant, which does not use differencing and substitution, thus is direct and faster, lastly it is very efficient to make the adjustment of more than two known points’ linear intersection with the initial values computed by the new approach. Numerical case is demonstrated.

Abstract: In order to study the effects of imported technology on Iranian architecture, a field study was conducted according to the views of architects and engineers involved in construction activities. At first, the literature subject was reviewed, then, the technology indexes, that affect the architecture, were identified. A questionnaire was prepared to recognize their effects, and ninety architects and engineers of Engineering Organization of Fars Province were surveyed. In this paper, the methodology of determination and prioritization of the indexes are studied and; the results of six indexes are discussed. According to the results, five of the indexes are negative. It is found that, lack of attention to the harmony between imported technology and social and cultural backgrounds has the most negative effect on the Iranian architecture during the past century. On the other hand buying and transferring professional imported technologies has been positive based on the participants’ idea.

Abstract: To improve the level of ship monitoring, ease the engineer’s working strength, improve the level of the shipping company regulation, the remote fault diagnosis system of ship’s engine room is designed with the comprehensive utilization of neural network, SQL Sever database, C/S structure, the Inmarsat system, etc. The system includes the data acquisition, data storage, the display and control of interface and wireless transmission. The results of application show that the system is stable, easy to use, modification with low cost, helpful for engineer knowing the state of engine room, convenient for unified supervision of the shipping company, improves the work efficiency, safeguards the shipping service.

Abstract: Bionic tech. applied in the building skin is important to the researching and application of the architectural bionic. Building skin bionic technology is a burgeoning technology, which mainly relies on high-tech, new resources, ecological theory, and sustainable development theory. And, it’s aiming is to set up a harmony relationship between the architecture and the environment. Building skin bionic technology concretes used in the structure, material, form, and some other fields of the building skin; in the main, it researches the functions and effect, energy-saving measures, ecological balance, and some other technique regions of building skin in vivo. Bionic technology used in building skin is one of the most important orientations of future architectural development. This text focus on three aspects about the application of bionic technology in the structure, material, and form of building skin, to elaborate the application theory, instance, and prospects of bionic technology.

Abstract: Dissipation of excess pore water pressure of saturation clay was discussed in the paper. Monotonic loading, unloading-reloading, and creep tests of one dimensional compression were performed to study the orderliness of dissipation of excess pore water pressure. In the drained consolidated tests, strain rate was changed step by step to check the effects of excess pore water pressure on effective axial stress. Creep tests were performed in different stage of loading and unloading procedure under different effective axial stress. In order to estimate the effects of excess pore water on effective axial stress more precisely, excess pore water pressure ratio was introduced. Test results show that: (1) excess pore water pressure changed gradually as strain rate changed abruptly, while excess pore water pressure ratio changed quickly; (2) excess pore water pressure maintained constant shortly after the change of strain rate during monotonic loading tests under small strain rate; (3) excess pore water pressure may be smaller than back pressure during unloading-reloading tests, in which, excess pore water pressure ratio is negative; (4) there neutral creep existed in unloading-creep-unloading procedure. Excess pore water pressure ratio equal to 0 and excess pore water pressure maintained a constant value equal to the back pressure in neutral creep.
