Abstract:With examples of three 6-storey RC frames by using an elasto-plastic dynamic analysis program PL-AFJD of plane frame, developed by the second author of this paper, the frames designed for different earthquake-intensity regions (intensity category 7, 8, 9 respectively) are analyzed nonlinearly under four ground motions at the action of rare earthquake. Three frames strictly conform to the National Standard GBJ10-89 and the dimensions of columns are changed once along the height. The structure designed on intensity category 7 shows a relatively small response, which could be sustained by the structure. Though the hinge formation in columns can not be prevented, the inelastic deformation of columns is not serious, the structure at intensity category 9 exhibits a relative strong response, but the deformation of most columns is within the capacity and the trend to form a soft-storey does not appear. It is the structure at intensity category 8 that shows a severe response. Though the visible soft-storey can not be found, the deformation of some columns is beyond the capacity of inelastic hysteretic deformation under certain inputs, which indicate the possibility of local collapse.The elementary analysis results demonstrate the different effectiveness of seismic provisions for three different earthquake-intensity regions, which may be a reference to the amendment of National Design Standard.

Abstract:This paper analyzes the heat transfer principle of temperature sensor fire detector, establishes mathematical model of heat transfer with considering the effect of radiation heat transfer and presents a new calculation method for the response time. The results of calculation show that when the environment temperature is rather low and the response temperature is set higher, the effect of radiation heat transfer on response time shouldn't be neglected. This paper may be helpful in appraising fire safety and designing alarm system.

Abstract:To overcome the disadvantages of traditional galvanized pipe, new types of water supply piping materials have been developed. Comparison and classification are made based on their characteristics such as thermal stability, resistance to pressure, expansion coefficient and thermal conductivity, resistance to water hammer, cost and easiness of installation. Furthermore, the characteristics were discussed according to their locations in buildings: distribution main line in each pressure zone, branch pipe in water closet and the main line. Finally, the conclusion about the principles for pipe selection according to its location in buildings is given.

A detailed discussion on how to offer chances for individual promotion is carried out and some viewpoints of how to harmonize the individual promotion with the corporation development are brought out.

Abstract:Dividing the bidding document into technical bidding and commercial bidding and scoring them respectively, then evaluating and awarding the bidding according to some principles and the fixed procedures and it may be the promising solution to problems existing in the bidding.

Abstract:The bidder can't make bold to withdraw the bid or to modify it in the period of validity of the bid. When the bid error takes place before decision on a tender, the bid is granted to modify or withdraw. After the contract has been entered into, it can be changed or canceled, then the bidder is given a remedy at law.

Abstract:The research of asymmetric structures' seismic response is quite active in foreign countries, but there area few research works in China. There are many structure's factors that influence the asymmetric structure's inelastic seismic response, so it is difficult to form consistent points for each factor which influences the structure's torsional response. In this paper, the status of research in this field is reviewed.
