        摘要：By using Hellinger-Reissner's calculus of variations,this paper presents the usual method with which the section strain distribution state of reinforced concrete member can be derived from the basic balance equation.This method is suitable for any difinite form of strain distribution of the compressional zone of concrete.It is made clear by calculation that if the compression zone of concrete has linear strain distribution in the deformation process,the strain of tension bar and the distribution mentioned above can satisfy the assumption of plane section multaneously.

        摘要：As a carrying body of culture,the achitecture reflects the achiev-ements and different levels of development of culture on various sides.The steady architectural skeleton is based on long-time sedimentation of culture in the historical periods.The super-steady mould that this skeleton expresses permeates the ideologies of Confucianism,Taoism and Buddhism.No matter what the kind of architecture is,it has the pubtic characters and temperaments reflecting the unified potential consciousness.This paper briefly analyses the vironment,overall,order, implication,confusion and seeking sameness of architecture in order to illustrate their importance in the contex of architecture.

        摘要：In general,the calculating result of a comparatively regular frame-shearing wall system in tall buildings,a 4-order differential equations are established according to the deformation-coordination of beams,columns and four boundary conditions.Then a series of formulas concerning internal forces and displacement is obtained These formulas are hyperbolic functions.This paper presents a method,which changes 4-order differential equations into 2-order and solves them by the expressions of new homogeneous solutionThen the formulas of internal forces and displacements become exponential functions By this method,the calculation is very convenient The result of suggested method agrees well with the general by comparison This paper is also applicable to buildings with some part of different height of storey or stiffness.
