Aiming at the advantages and disadvantages of triangle and rhombic main truss-types and their respective scopes of application, a comparative analysis for the two commonly used truss-type formtravellers has been done. The main factors for analysis are load bearing capability, structural rigidity, steel consumption and working space. It provides a useful reference for the design and selection of the formtraveller. In addition, for the overall deformation of the formtraveller, it is structural optimized while height of column of the truss and suspenders are changed. Finally, the analysis results show the reasonable height of the column and suspender arrangement to achieve the construction target of safety and cost-effectiveness.

Sun basking is the most common method for freshwater turtles, such as the European pond turtle, to maintain optimal body temperature. The attributes of the macro- and microhabitat features around the basking sites affect the basking site selection of the European pond turtle. To protect the European pond turtle, it is important to know the basking habits among the biological characteristics of the species, along with the effects of the habitat characteristics and the choice of the type of basking sites. The purpose of our research was to detect the effects of macro- and microhabitat features on the selection of basking sites. We wanted to determine basking site type selection according to the carapace length classes and if there is any difference in the choice of basking trunks and branches with different thicknesses. Turtles choose basking sites with less closed vegetation in their environment. We have detected seasonal differences in the microhabitat features. The closing reed and Typha sp. had a negative effect on the number of observed basking turtles. The most popular type of basking sites in the pond system was the commonly occurred fallen tree trunks and branches in the water, regardless of turtle body size. Most turtles used thinner tree trunks and branches for basking. In the meantime, we found differences in the choice of basking trunks between the turtles with different body sizes. Younger turtles with smaller bodies appeared in larger numbers on emergent branches with smaller diameters.
