By upgrading of engineering test a number of physical, chemical and mechanical properties of the data, after five indicators of soil improved with the high-speed railway and the requirements of comparison, a high-speed rail come to use the improved soil, the method of some conclusions. Lime and soil interaction can be divided into four categories : First, ion exchange; Second crystallization sclerosis; Third ash; Fourth carbonated role. The principle is modified cement-soil cement in soil constitutes a solid core, in all the holes to form the skeleton of cement hydration, bound to soil particles. Through five indoor soil improvement, raw materials and on-site tests showed five improved soil could be used as high-speed railway subgrade fill the bottom of the bed, a test achieved the requirements to test the comparative technical and economic integration can be drawn from the high plasticity index clay could lime powder (sandy) soil cement may improve conclusions. Use nuclear density, filling sand method, three cutting techniques and methods compaction factor, it is found from the normal nuclear density greater, as high-speed railway should not be inferred from the quality of detection means compacted subgrade. Compaction and the times of the relationship between the coefficients derived from the test plan and the best the times of their relationship. After testing, the cement-soil mixture from the RCC to be controlled after less than four hours, lime and soil should not exceed 12 hours, if the pressure is lagging a long time, and then destroyed when it rolled improved soil early strength, leading to the eventual degradation compaction hard-compressed to be continuous rolling, parked for some time supplemented pressure compaction factor increased little. Improve soil strength in a certain time frame, with the additional time, it is proposed to be completed within 24 hours began rolling K30 test, the results may be distorted. Construction has improved soil mixing plant, road courses mixed mixing three have formed a more mature work, through a stringent process control can meet the quality requirements for passenger lanes. After three methods, we found that the market-mix not only overcome the "Mixed" Construction irregularity, human factors large and thickness of the requirements are strict, admixture content control difficulty and could easily lead to pollution wrong, solves the "Mixing Plant Act" low efficiency and high costs, economic, applicable, operational characteristics of this stage can be widely used. The curing agent for the improvement of the railway project is still relatively little test, the test results meet the requirement for passenger lanes relatively low cost for future exploration done to broaden the scope of modifiers. In short, the solution is to improve quality through testing that the filler packing lack of effective ways to rece the construction cost.

Abstract
This paper is concerned with second-order plastic hinge analysis of three-dimensional frame structures. The beam–column formulation
is based on the use of stability interpolation functions for the transverse displacements, and considers the elastic coupling
effects between axial, flexural and torsional displacements. The developed computer program can be used to predict accurately the
elastic flexural buckling load of columns and frames by modelling each physical member as one element. It can also be used to
predict the elastic buckling loads associated with axial-torsional and lateral-torsional instabilities, which are essential for predicting
the nonlinear behaviour of space frame structures. The member bowing effect and initial out-of-straightness are also considered so
that the nonlinear spatial behaviour of structures can be captured with fewer elements per member. Material nonlinearity is modelled
by using the concentrated plastic hinge approach. Plastic hinge between the member ends is allowed to occur. Numerical examples
including both geometric and material nonlinearities are used to demonstrate the robustness, accuracy and efficiency of the proposed
analytical method and computer program. Ó 2000 Elsevier Science Ltd. All rights reserved.

1. Introction
Two-dimensional (2-D) plastic hinge analysis of plane
frames composed of members with compact section,
fully braced out-of-plane, has been the subject for investigation
in recent years. The theory for advanced inelastic
analysis of rigid and semi-rigid 2-D frames has been
well developed and verified by tests [1,2]. These analysis
methods fulfil the requirements for the prediction of
member strength and stability, with some constraints,
satisfying the conventional column and beam–column
design limit-state checks. Although there have been
much work on the plastic hinge analysis of 3-D frame
structures, the issues related to different theoretical and
numerical formulations and their accuracy and efficiency
in solving large frameworks are not addressed well. The
research presented in this paper is an extension of
advanced analysis for 2-D frames [2] to 3-D frames [3–
5], reflecting the current trend towards the rationalisation
of advanced analysis proceres.

Abstract
The purpose of the design is to do the anti-seismic design in the longitudinal frames of axis 2、3、7、8. When the directions of the frames is determined, firstly the weight of each floor is calculated .Then the vibrate cycle is calculated by utilizing the peak-displacement method, then making the amount of the horizontal seismic force can be got by way of the bottom-shear force method. The seismic force can be assigned according to the shearing stiffness of the frames of the different axis. Then the internal force (bending moment, shearing force and axial force ) in the structure under the horizontal loads can be easily calculated. After the determination of the internal force under the dead and live loads, the combination of internal force can be made by using the Excel software, whose purpose is to find one or several sets of the most adverse internal force of the wall limbs and the coterminous girders, which will be the basis of protracting the reinforcing drawings of the components. The design of the stairs is also be approached by calculating the internal force and reinforcing such components as landing slab, step board and landing girder whose shop drawings are completed in the end.
Keywords : frames, structural design, anti-seismic design
