High strength stainless steel wire mesh-polymer mortar reinforcement method was a kind of advanced reinforcement technique.The present study attempted to do a model analysis on the test of the high strength steel wire mesh-polymer mortar reinforcement of less stress beams by using finite element software ANSYS. The study was conducted through the analysis of the three factors of the tested bending reinforcement beam’s deflection, deformation and stress and comparison of the changes of the beam’s ultimate load and failure mode before and after reinforcement.The results of ANSYS analysis and the test showed that the failure mode shifts from less reinforcement damaged into reinforcement destruction;the crack loading value of the reinforced beams increased indicating that the beam bottom reinforcement layer had a significant effect on the increase of the beam’s crack loading. Increased significantly compared to non-reinforced ultimate bearing capacity of reinforced beams. the ANSYS finite element simulation agrees well with the experimental value.

Based on the experimental study of shear strengthened of reinforced concrete rectangular beam strengthened by high-strength steel wire mesh and polymer mortar , the finite element extended analysis was used. The finite element analysis software showed that with the increasing of the strand dosage and reinforcement strand length,the shear strength and stiffness of strengthened members improved . However,with the increasing of shear span ratio , the shear strength and stiffness reduced obviously .

A steel reinforced plastic pipe (PSP), which is composed of two layers of high density polyethylene (HDPE) matrix and a high strength steel wire mesh skeleton, has wide applications in many industrial areas, such as gas and petroleum transportation, etc. In order to achieve higher efficency and lower costs, a large diameter PSP has been developed. However, requirements of the large diameter PSP in safety and economy are much higher, compared with those small diameter PSPs, and some potential problems should be taken into account. In this paper, relevant structural parameters of the large diameter PSP are determined, based on a previously proposed model, and a short-term burst test is carried out. The experiment results agree with the theoretical results quite well. Subsequently, the resistance of vertical pressure and uniform external pressure are evaluated by using experiment investigation and finite element method, respectively. And corresponding results indicate the large diameter PSP with determined structural parameters is qualified to use.

The pre-stressed stainless steel wire mesh (SSWM) –mortar (M) is a pre-stressed laminate structure for structural strengthening and rehabilitation. Pre-stressing the stainless steel wire mesh is the key technology for engineering practice. A jogged anchor is proposed for anchoring large diameter SSWM conveniently. The flexural performances of 5 damaged RC beams strengthened by pre-stressed SSWM-M and one referential RC beam were tested. The experimental results indicates that the large diameter pre-stressed SSWM-M has a better performance in controlling the crack growth, restoring the flexural capacity and stiffness than the small diameter pre-stressed SSWM-M.

This paper presents the effect of warp knit textile reinforcement in ferrocement laminates. In general, steel wire mesh is used as ferrocement reinforcement, which is often known as chicken mesh. The need for the replacement of steel mesh is the problem of corrosion, which reduces the durability of ferrocement laminate. High performance synthetic fibres and fabrics are constantly used in various research works as reinforcement in concrete. In this paper, an attempt was made to incorporate three different nylon warp knit mesh structures in the place of chicken mesh. Ferrocement composites were produced with chicken mesh and nylon warp knit fabrics. The flexural properties of ferrocement laminates were analysed in terms of the first crack load, ultimate load, energy absorption capacity and ductility factor. Nylon square mesh with 3 layers in the reinforcement has a 2.5 kN first crack load and 3.36 kN ultimate load, which is higher than chicken mesh reinforcement in ferrocement laminate. The results show that there is an improvement in the flexural properties of ferrocement laminates reinforced with a nylon warp knit structure. The flexural parameters have a direct relationship with the number of layers used in the reinforcement.
