A Study on Characteristics of Elasto_Plastic DisplacementResponse of Structures Under Seismic Action
摘要：The characteristics of elasto-plastic displacement response of structures subjected to different types of ground motions are studied and generalized in this paper.667|985|0更新时间：2023-11-28 - 摘要：This paper introduces the importance of developing the Ground-Source Heat pump and describes the prospects of it.with the method used abroad to acquire the temperature profiles within surrounding soil of the underground heat exchanger with buried tubes, in this paper the line heat source theory and thermal resistance network analysis method were used to set up the heat transfer model.The original temperature of the ground is determined by calculation and is compared with test results. Experiments of running single tube and running three series connection tubes are carried out on the built underground exchangers of vertical buried tube type.And the data which can provide reference for the Ground-Soure Heat pump technique are acquired.901|1032|0更新时间：2023-11-28

Theoretical Analysis of Load Capacity of EccentricalReinforced Concrete Columns with Concerete Cover
摘要：Based on the plane_section hypothesis of combination section,this paper describes the section strains of reinforced concrete columns with concrete cover under initial axial pressure and analyses the height of relative limit compression area and the stress of concrete and reinforcing bar of combination section in ultimate state.Meanwhile,the paper proposes practical calculation method of load capacity.824|919|0更新时间：2023-11-28 - 摘要：This paper covers a new long phosphorescent material which absorbs daylight or lamp light and saves the light during the day and will illuminate after exposure,This nonradioactive, non_poisonous illuminant material will receive ultra_violet and visible lights and its luminous intensity is 10 times more than that of previous phosphorescent materials,meanwhile with more than 24 hrs phosphorescent time and 10 years lifetime,this luminous material may be used for the illuminating purposes such as indicator light.699|21|0更新时间：2023-11-28
- 摘要：On the basis of quaility accident cases in engineering, this paper presents the necessity of establishing the mechanism of regulation standards on engineering quaility for whole construction work. This paper compares the technology standards with regulation standards on engineering quaility, puts forward the idea of regulation standards on engineering quaility for whole construction, analyses and studies the procedure norm, accounting system, management mechanism,auditing supervision and risk forecasting technique on engineering quaility in entity related with whole construction, under consideration with the reality of interaction relationship on engineering quaility and engineering financing in our county, finally ,explores and illustrates the positive appoarch which is used for establishing the mechanism of regulation standards on construction engineering quaility.734|23|0更新时间：2023-11-28
- 摘要：Selecting the constructional address is a key problems on the investment decision of the cons-tructional project.This paper establishes the general methods of multi-target decision on the constrcutional address,and using AHP and the Efficiency coefficient Method(ECM) to advance the Synthetical System Method(SSM)of multi-target decision and the example of its applicalion is given.671|21|0更新时间：2023-11-28
- 摘要：Having demonstrated the importance of establishing the appraisal system for the effect of investment control by supervision,this paper designs not only the appraisal model for this problem by citing the basic theories of Analytic Hierarchy Process but also interprets the application conditions and specific approach of the model.Finally,the paper introduces an actual project case by using the model and analyzes the general practical application environment of the model.622|13|0更新时间：2023-11-28

- 摘要：This paper deals with the linear equations algorithm for quadratic programming problems with equality constraints.In this paper the optimality conditions were used for programming problem with equality constraints and then a linear equation was established. Finally the solution of these leads to optimal solution of quadratic programming problems.596|12|0更新时间：2023-11-28
- 摘要：According to multivariant linear regression analysis for Economies of Scale of construction industry,the paper argues that it is unreasonable for taking the Economies of Scale as the economical course of Construction Enterprise Group (CEG) as it would misguide us.This paper gives a more reasonable interpretation.There are Economies of Scope only if the core enterprises take advantage of their more advanced technology,more scientific administration,and more valuable message to integrate other enterprises vertically and have multivariant management,and develop Economies of Scope.The Economies of Scope Theory can give us a lot of useful messages for the foundation and resystematizing of CEG.489|12|0更新时间：2023-11-28
- 摘要：The basic concepts of ground attributes and Synthetic Digital Tarrain Model(SDTM) are introduced.An highly adaptable on_site realtime modeling method and on algorithms based arbitrary curves are suggested.The application of this method in high grade highway survey are introduced.585|9|0更新时间：2023-11-28
