The purpose of this research is to find out the influence Fundamental analysis ( of price earning ratio, earning per share, dividend per share, and dividend payout ratio) to the enhancement of mining companies’ stock price in 2014 – 2018 periods. The sample collection technique has been done by using purposive sampling method, and the samples are 6 companies. The statistic test method has been done by using multiple linier regression analysis. The independent variables in this research are price earning ratio, earning per share, dividend per share, and dividend payout ratio. The dependent variable is stock price. The result of this research show that price earning ratio, earning per share, dividend per share have significant and positive influence to the stock price. Meanwhile, dividend payout ratio have significant and negative influence to the stock price. It can be seen from the result of partial coefficient determination and it can be concluded that the variable which has dominant influence to the stock price is dividend per share because its partial coefficient determination is bigger than other independent variables.

Introduction: Based on the experimental results of cold-formed thin-walled steel lipped channel sections, the uncertainty of calculating mode of load-carrying capacity using effective width method considering distortional buckling for different material types cold-formed steel compressed members was researched, and the uncertainties of material strength and geometric characteristics of the typical sections were statistically analyzed. Methods: According to the recommended resistance of partial coefficient in the draft of Technical code of cold-formed steel structures (GB50018-), the reliability indexes of cold-formed thin-walled steel lipped channel sections under compression were investigated using the improved first-order second-moment method considering different possible external loading combinations. Results: The analyzed results show that, using the recommended resistance partial coefficient in the code draft, the reliability indexes of the compressed members with width-thickness ratio within the limitation of code draft can well met the target reliability index. The suitability of the corresponding calculating modes of load-carrying capacity considering distortional buckling was established.

Partial coefficient finite element method is a new method of analyzing the stability of jointed rock slope. Partial coefficient Finite element analysis of joints rock slope stability, the calculation accuracy will be influenced by many factors, Such as the yield criterion, the mechanical parameters of rock mass, the computing grid, etc. In this paper, combined with example analyzed the impact of these factors on the partial coefficient method calculation accuracy. Considering material partial coefficients of slope’s weak layer, then, the weak layer is reduced by the strength reduction method. Analysis results show that: Using partial coefficient method analysis of stability of rock slope, under the associated flow rule, should choose Mohr-Coulomb inscribed circle criterion. In addition, when using Mohr - Coulomb inscribed circle criterion, the modulus of elasticity and poison’s ratio on the calculation results can be ignored. And with a few elements ideal result can be deduced.

The relevant specifications in China make the relevant regulations to guarantee the stability of the shear wall and provide the check formula. This paper discusses the rationality of the calculations on the shear wall stability from the perspective of the reliability index, and calculates the reliability index in the state of the shear wall’s instability limit by means of JC method, the result shows: the current regulations can not guarantee the requirement that the reliability index of the shear wall is not less than the target reliability index. Based on the target reliability index, load partial coefficient and load, geometric dimension probability statistical parameter, this paper uses JC method to make inverse operation, calculates the shear wall stable resistance force partial coefficient under four types of load effect combinations, and analyzes the influence of load effect ratio, thus getting the shear wall stable utmost limit load best resistance partial coefficient.
