Abstract:The beam-plate foundation is divided into two parts.The boundary element methods areapplied to analyze the plates with Winklermodel.The finite element methods are used to evaluate thebeams The coupling equation is obtained by the coodination of both force and displacement.

Abstract:This paper describes the evolution of ponding roofs, and recommends a kind of ponding roofcovered by floating insulators, which has excellent thermal performance. A new opinion on dynamicthermal decrement is presented, and its main influening factors are analyzed.

Abstract:A model for indoor thermal comfort assessment was investigated in this paper. By using this model, the indoor thermal comfort of low energy consumption buildingwith buried pipe system was evaluated. The result shows that the buried pipe ventilationcan improve indoor thermal comfort in hot climates.

Abstract:In this paper the, structural reliability theory is used to analse the reliablity of ultimatestates of complex pile foundation by means of a project example. further research is carried out on suchaspects as sensitivity of basic variables, of every resistant relationship between index of reliability andsafety fortor, influence on index of reliablity by platform which subjects to actions.

Abstract:This paper discussed applying ELECTRE method to select the Commodityhouses in multi-objection. In order to define the grades of the commodity houses, a quantitative method on pricing the commodity houses according to their grades for Real EstateBusiness Centre or price departments was provided.

Abstract:According to national law and code, this paper discusses the content and requirement of legal adjustment in urban land leasehold relevant to the rules of payable landuse.

Abstract:In this paper, some methods for realiaing speed feedback are analnd . A new idea to realizespeed feedback without without tachometer generators is proposed and its feasibility is verified by studying anexperimental provision.

Abstract:Rectangle fin is widely used in different kinds of heat exchangrs. Convection heat transfercoefficient distribution over the fin surface is one of the theorehcal problems in research on enhancement of heat transfer. In this paper, a tube with an attached rectangular fin is used for a model and thefin surface is divided into a network of nodes by the finite difference techinque. When the wind velocityis u= 4. 5 m/s. the temperature distribution of discretization is obtained by experimental measurement,then the convection heat transfer coefficient of all nodes are soved by using the methed of inverse heatconduction problem. Through checking with heat balance methed, the results show that the solution cancorrectly express the actual heat transfer situation.This result is useful to experimental research onenhancement of heat transfer for finned for heat exchangers.

Abstract:In this paper a nonsteady heat flux equation for car body is established and the formulationof transmission function coeficient of the cooling load is derived. The composition of the automobile airconditioner's cooling load has been analysed and a computer program for calculating the cooling loadhas been compiled, It has proved to be exact from the example, So these results are of practical value.

Abstract:This article analyses the hydraulic reliability of gas -transport network under high andmedium pressure in detail, To increase the hydraulic reliability, it is available to improve the send outpressure in permissible condition.

Abstract:This paper, on the basis of discussing IB's conntation, proposes the aspects which constitute the fundamental philosophy of IBMS, i. e. integrity. entirety. information and optimality. At last,the trends of IBMS development are explored.

Abstract:Through actuality analyses of commeroial house prices and inhabitatS' income in ourcountry, comparisons of city house prices between countries in the world are carried out and it ispointed out that in our country the house price is much higher than inhabitants' income that they cannot afford it. Based on studies on reasons of such high house price, ways to cut down the high price areexplored.

Abstract:This paper focuses on the typical regular R. C frame structure. Considering the fact thatframe structure still works at its elastic stage under frequent horizontal seismic action, and based on theprinciple of structure optimum design and the theory of anti - seismic design, a structure optimum modewhose control objective is apex lateral displacement is presental for frame structure.And an optimunobjective function is consequently determined . Finally this paper gives the calculation formula for sections'dimension of beams and columns of typical regular R. C frame structure. And the form of beamsnd columns optimum rigidity ratio is presented for engineers' reference.

Abstract:The three development stages of building water service, the reason for its renaming and contents for each stage are reviewed in this paper. Also, the problems whichshould be solved in the coming days are presented.

Abstract:This paper the expounds intension of the safety systems engineering, makingbetter systematic analyses on the cause of formation of accidents. And an idea using theprinciples and method of the safety system engineering to strengthen safe administrationin building is proposed.

Abstract:This paper systematically presents the experiment about the adhesive and shearing strengthbetween the concrete member poured with two kinds of steel form and the cement mortar on the membersurface. By the comparison of three groups of experiments, this paper draws a conlusion tha the adhesive and shearing strentgh between concrete member and cement mortar could be considerably increased if the special-shaped steel form was applied.

Abstract:Single-crystal casts are obtained with the technology of directional solidification, The reasonable technique is discussed and the growing process of single crystal is analyzed.

Abstract:This paper developed out coordinate equations and equation of strain energy for suspensionand network structure made of linear hardening materials.Then displacements and horizontal forces ofthe network are determined by principle of minimum potential energy.

Abstract:In view of some puzzles in descriptive geometry, several typical example were used to explain the applicaions of the method of assistant sphrical surface in this paper With such method theproblems in descriptive geometry could be solved simply.
