static computation
1.Slanting heterogeneous type arched bridge is a new type of space composite structure system with specific characteristics. this paper takes the HanJiang bridge as an example,introduces the continuously multi-spans slanting arched bridge design and the arrangement continuously, analyzes the bridge structure system characteristic,through the plane and the spatial static computation,indicates entire bridge structural design stress reasonable,arches the section,the suspension link,the tie bar,box beam,supports the concrete storage stress reserve to be moderate,each cross displacement satisfies the norm requirements;
2.A STUDY OF THE STATIC STRENGTH CHECKING COMPUTATION METHODS FOR SMALL—END BUSH OF THE CONNECTING ROD IN THE MODEL R175 DIESEL ENGINE
3.By utilizing Ⅰ—DEAS software,static strength finite element analysis and computation are carried out on 25 5m air conditioned semi cushioned berth sleeping cars.
4.In this paper,using the finite element method,we completed the computation of static rigidity for a lathe bed.
5.Using the finite element structural analysis programme JJSAP, we have performed the analysis of static characteristics of the swivel-frame complex of the articulated vibratory compactor SP-48 of INGERSOLL-RAND Company. In the programme the contact problem in the complex has been specially handled effectively. Through the computation and experiment, the strength and stiffness properties have been analyzed and the weak points in the complex have been found, which laid a foundation for optimization of the structural parameters of the complex.
6.A structure computation model for analyzing the DLCPS system has been founded based on MIDAS software,which considers the pier limb as a beam and the base of pier as a fixed end,and the presented model is applied to study the static behaviors,dynamic characteristics and seismic responses of the DLCPS.
7.With the compaction of shale as a two-dimensional function of depth-of-burial versus time, the formulae for computation of the velocity, volume and coefficient of compaction-fluid flow under. overstatic pressure drive are derived, based on data from sonic logging in shale and the differential equations of the relationship between the over-static pressure gradient of shale and its porosity, permeability and viscosity of the fluid as proposed by Smith, etal.
8.The computation results indicate that when the earth-rock dam with the straight clay core on thick moraine cover foundation is designed, the design criterion for the earth-rock dam with straight clay core directly built on the bed-rock can be adopted for the design criterion of dynamic stability of dam itself, but the dam feet and the dam clay core feet should be reinforced for static stability.
