Introduction The tensioned cable-membrane structure is a flexible space structure system which is formed by cable and membrane materials working together after forming.
Fig. 1 Schematic diagram Finite element analysis method of friction contact between cable and membrane The cable is meshed with 30 Link10 elements in ANSYS,and membrane surface is meshed with some shell41 triangular plane stress shell elements.The friction contact between the valley cable and membrane surface is simulated by contact elements.Because friction contact is a irreversible complex loading process,incremental iterative method for solving is applied[6].There are three contact states:STAT=0 or 1,elements are not closed of far or near contact;STAT=2,elements are sliding contact;STAT=3,elements are adhesive contact[7].Friction coefficient is introduced and the following assumptions are made: Small strain, complying with HOOKE’s law;Membrane is an orthotropic elastic material, deformations of material always maintain the vertical axis;Considering friction contact between cables and membranes.
The friction contact between the valley cable and membrane surface is simulated by node-surface contact elements in ANSYS,detailed steps are as follows:Establishing planar projection geometric model;Setting virtual cable and membrane elastic moduluses;Establishing element types,real constants,material properties and initial pre-tensions under virtual cable and membrane elastic moduluses;Meshing geometric model;Selecting node-surface contact elements,and inputting friction coefficient;Establishing edge conditions and enhancing displacements according to elevations of edge control points between true structures and planar projection models;After the first form-finding updating nodes coordinates,setting enhancing displacements of edge control points zero;Restoring true elastic moduluses,resetting true cable pre-tension and membrane pre-tension; Performing the first equilibrium iteration solution;Re-updating nodes coordinates and equilibrium iteration solution until results tolerance is up

In this study, with iron ore tailings and CaO as raw materials, three belite cement clinker samples were prepared in a muffle furnace at 1400℃ for 10, 20 and 30 minutes respectively.
From700℃ to 1100℃ the sample weight tends to be stable, followed by slight weight loss when temperature was passing 1250℃, which may be caused by volatilized materials loss with air flow, such as K, Na, S, Cl and some other elements.

Graphene (GN), a novel one-atom-thick two-dimensional (2D) graphitic material, is a rapidly rising star in the field of materials science [17].
For bulk carbon materials, environmental remediation is the most meaningful application and widely used [21].
Thus, FGN could be a good replacement for conventional adsorption materials.
