It is generally considered that the seismic response of Arched Corrugated Steel Roof(ACSR) is not the control factor of structure design because of its light weight,but the wind-induced dynamic responses on the structure is significant,Therefore,more attention should paid on it.In this paper,ACSR was modeled by element Shell63 by ANSYS commercial software,and the frequency domain analysis on wind-induced dynamic responses of ACSR was carried out.The conclusion demonstrates that the pulsating wind load is a vary harmful for the structure of ACSR,and the suggested coefficient of wind vibration was given.
To overcome the shortcoming of traditional masonry mortar for air-entrained concrete such as poor water retention,low bonding strength and liabititv to cracking,a new type masonry mortar for air-entrained concrete with better performance than that by JC890-2001 standard was prepared.The effects of water-retentive agent,redispersible latex powder and expansive agent on masonry mortar were studied,and their modified mechanisms were discussed respectively.
It is necessary to simplify the capacity spectrum into bilinear form so as to get characteristic point of hysteretic bone curve(especially the yield point and the yielded stiffness),ductility and equivalent damping of the structure.Three general methods of calculating yield point and yielded stiffness of equivalent SDOF are introduced and the yield point and the yielded stiffness of three frame structures are compared using above given methods in this paper.The hysteretic bone curves of equivalent SDOF are decided by the equivalent yield force and displacement,the maximum plastic displacements of equivalent SDOF under rare earthquake are calculated,and it is compared with the maximum plastic displacements of member structures using nonlinear dynamic analysis.Finally,the advice of simplifying capacity spectrum is advanced.
By the way of experiment and analysis of two story and one bay reinforced concrete frames, namely a with weaker and a column with equally strong beam frame, the features of internal force redistribution are investigated and an elementary comparison about bending moment redistribution of kinds of frames namely the column with weaker beam, with weaker and column with equally strong beam is given. Through this comparison, the objective existence of such three kinds of frame is proven, the moment redistribution is different for each and for the moment modulation, the elastic moment diagram and the difference of the internal force redistribution in different frames should be considered together.
The impulse responses and other acoustical parameters of Huangpu Teenager Palace were measured. Meanwhile, the acoustical simulation based on software ODEON was carried out as well. The parameters based on computer simulation are compared with the measured ones. This case study shows that the auralization technique based on computer simulation can be used for predicting the acoustical quality of a hall at its design stage.
The evaluation of competence for site manager has the characteristics of multi-factor, fuzziness and complexity. In this paper, taking use of fuzzy evaluation and multi-factor to evaluate the competence of site manager based on his performance and sets forward the evaluation based on an actual example. As a part one of the paper, mainly the indexes and weight for evaluation are formulated.
In order to research energy efficiency design of public buildings,the large and medium scale of typical department stores in Chongqing are chosen as objects and twelve stores are investigated about their operational energy.Based on the investigation results,the composition and features of operational energy are analyzed;it is shown that the short of effective measures in respect of architectural design leads to the high power consumption in department stores.According to the local climate and environment characteristics, this paper puts forward concept of holistic energy efficiency and offers series of design strategies which lead to energy conservation in stores,such as regarding climate as resources and applying appropriate technology to attain energy efficiency.
In this paper, the conditions of air-cooled heat pump operation indoors in winter are analyzed. The corresponding performance of air-cooled heat pump operation is gained. The ventilation condition for stable operation of air-cooled heat pump indoors in winter is found. At the same time, the experimental results are approved by the actual operation effect.
The forecasting model of ANFIS(Adaptive Neuro-Fuzzy Inference System) is applied to forecast the displacement values at observation point of the slope at the Shilong garden of Chongqing Shizitan Hydroelectric Power Plant.The forecast results show that the errors between the forecast values and the observation values are very little.It shows that this model may be well applied for the forecast of the displacement in the deformation of the slopes.
The specific properties of soft clay are characterized by higher void ratio, lower permeability and higher compressibility, the consolidation settlement of soft clay is affected by the imposed stress history, the stress paths, the consolidation pressure and the soil properties. In this paper, the porous media theory based on the mixture theory was applied in the study on the consolidation settlement of soft clay, which was more rigorous than the conventional consolidation settlement theory and the coupling between soil and water can be taken into account in the analysis.
At present, in the evaluation process of the real estate value the material form is mainly concentrated on, while the value brought by the real estate brand are usually neglected. In this paper, considering the particularity of the real estate brand evaluation, the method of network analysis is adopted. In the evaluation process, the evaluation method of excess income law are developed by leading the thoughts and methods of the fuzzy set theory, and a systematic assess model is found. Then, an example is given as illustration. At last, the appraise about the application of the model is made.
In this paper the theory of Fuzzy Mathematics is used to set up the case-based reasoning(CBR) mathematic model system on the price-estimation of the land-rental and the related process and conditions of its application are suggested.The calculation example of CBR in land business demonstrates that the CBR model is effective;it can be used as the reference for the decision-making on estimating the price in land business.
This paper analyzes the causes that contribute to listed companies' credit risk,and then formulates a logistic model of listed companies' credit in which the interest rate safeguard multiplier and turnover rate of inventory are taken as key indices through handling the data of the companies' annual reports.The listed companies' credit after one year of operation can be evaluated by using this model.
With the mixing of internal and international markets, many excellent foreign project management companies will invest in China. Facing the increasingly drastic competition of project management market, China's project management enterprise must catch the opportunity, accepting the challenge and creating a brand. In this paper, the present situation and problems of creating a brand of project management enterprise in China are analyzed. It brings forward the ways of creating management enterprise brand through intensifying consciousness of brand, building up a conception of brand capital, strengthening the construction of enterprise, improving consciousness of service, managing strictly and canonically, enhancing the service and improving staff training, setting up advanced management strategy and enhancing competition of enterprise.
For making the theoretic results close to the fact,two methods used to calculate the internal force of beams with finite length bearing several point loads and on soil foundation were compared.These two methods were based on the Winkler's assumption and the half-space elastic foundation theory respectively.Through theoretic analysis,the difference between the two methods was found.And with the aid of FLAC~(3D) analysis,it was clear that the results deduced by the method based on the Winkler's assumption were more close to the fact.
