The modern characteristics of distribution of the tectonic stress field in the northern part of North-south Seismic Belt are studied in this paper with distortion analogy, ordenary optic elastics and the simulated test of optic elastics of laser holography under various force sources. The paper deals with the principal compression stress, the main tension stress and their directions in this region. The isorithm of the principal compression stress in the region is given in this paper as well. Thus it can be known from the test mentioned above the stress value in the aetion of unified stress field in every segment of this region. With Moll strength theory, the seismicity here is made an analysis and a researeh is conducted to the. relation between the modern features of distribution of the (?)ionie stress field and epicentral migration.

The testing of 10 two span R.C. continous deep beams are reported in this paper. Analyses have been carried out by using computer program based on nonlinear finite element method. The distributions of sectional stresses for such deep beams with various span depth ratios are described. The envelop values of internal forces such as elestic moments and shear forces have been calculated and listed in tables. Some formulas for computing flexural strengh of deep beam sections at mid-span or near supports for determining the critical reinforcement ratio and for calculating the load bearing capacity of continous beams are derived. The allowable maximum nominal shear stress has assessed as 0.15Ra. Comparisons between the results of tests and these of calculations are shown good agreement. The moment redistrbution of two span continous deep beams after cracking and at first yeilding of main tension steel bars are studied.

Using three-dimension photoelastic test and finite element, we determined and analysed the stress distribution on the patella in a sfngle-leg standing position with knee flexion of 30°, 40°, 60°, 75°and 90°. The results showed that as the knee flexion degree was increased, the patella gradually became a bent component, the central part of its surface beefed the greatest tension stress, its base and apex beared the secondary, and Its back heated compression stress, both stresses being the greatest In 90°-knee...

用三维光弹实验方法和有限元分析法,分析髌骨在正常单足站立位屈膝15°、30°、45°、60°、75°、90°等状态下的应力分布规律。结果显示:随着屈膝度增加,髌骨明显变为一受弯构件,其表面中部承受拉应力最大,髌底髌尖次之,髌骨后部承受压应力。屈膝90°时拉压应力均最大。额状面上髌骨的主拉应力迹线略呈“V”形,且受Q角影响而不同程度地向外偏移,屈膝30°时偏移最显著。
