Interpolation method for the calculation of wind pressure distributions on long-span roofs;

Due to the airflow separation and re-attachment,wind pressure distribution on long-span roofs is complicated.

With the exhibition project of the Yangling Tombs of the Han Dynasty in the background,this paper brings forward the design and calculaton of prestressed concrete T beams with high load and low high-span ratio,combined with a great deal of domestic research datum and production.

The ground surface settlement of different thickness-span ratios and high-span ratios of metro tunnel are analyzed in this paper,and the maximum ground settlement curve under different thickness-span ratios and high-span ratios are gave in the end.

Utilizing finite element program-ANSYS the variation regularities of in-plane buckling critical load of basket handle arch with the changes of central angle 2α of middle arch,depth-span ratio H/L and central angle 2α_1 of side arch are studied.

The design of these large span-to-height ratio and large span secondary floor beams is presented.

Concrete beam span-depth ratio of satisfying loading capacity and deflection crack limit

A comprehensive study on the span-depth ratio of the reinforced concrete beams is made and the range of limited values for the span-depth ratio of beams is given in this paper.

This paper studies the relationship between the span-depth ratio and the various properties of the reinforced concrete cantilever and gives the ranges of limited values for the span depth ratio of cantilever beam.
