The lateral stiffness factor α is deduced and used to modify the effective length coefficient which calculates sway frame s second-order effect such as the P-Δ method,second-order elastic analysis method and double second-order effect method.

The calculation formula of the influence degree is advanced, number of the influence degree is computed, figure of influence degree is drawn, and mineable coal seam of each producing area is quantitatively evaluated.

Referring to the information abroad, some i nfluence factors of colorimetry of cement clinker were compared and analyzed, an d the influence degrees of the factors were presented.

On the basis of the traffic impact analysis of Beijing,referring to current appraising methods of traffic evaluation of influence degree in the United States of America,the United Kingdom,Hongkong etc, the logical evaluation target system of traffic impact degree is selected and a two-level .

An analytical method for stress field of massive concrete considering temperature effect;

Research on pressure measurement model using surface wave considering temperature effect;

This paper illustrates the temperature effect law at different stages of construction of Yamen Bridge, and provides the scientific bases for temperature effect compensation, correct determination or reasonable selection of formwork elevation, and proper time for cable force measurement in accordance with the theoretical analysis and field measurements of the bridge under construction.
