in this paper the traditional covering plaster of masonry buildings is supplied with polypropylene and steel fiber to enhance their seismic behavior. the plaster mix proportion is determined by some initial mortar tests. also, one story, single span masonry building specimen plastered with different mortars is tested on a shaking table 8 times under a seismic input and the performance of the sp...

Strengthening of existing circular reinforced concrete columns by CFRP confinement

the creep behavior of basalt fiber reinforced epoxy (bfre) and glass fiber reinforced epoxy (gfre) composites was studied through tensile testing at high temperature. to study the effect of reinforcing epoxy, the micro glass powder (mgp) was added at various volume percentage into the epoxy resin in bfre composites. the initial strain for all the specimens were evaluated and compared with each ...

We developed a hybrid SWP with organic and inorganic heat insulating materials as the core material verified performance of fire resistance mechanics during development process. By using both together, it exhibits better than alone. In particular, specifications fiber-reinforced plaster board plate, which was superior to rockwool in terms mechanics, also showed excellent ISO 13784-1 test.

A Portland cement plaster wall system has many positive features, but one of the physical properties that it does not possess is flexural strength. It is because of the inability of the Portland cement plaster membrane to bend or flex that glass fiber strands were used in Portland cementbased plaster. There are various types of synthetic fibers on the market that will provide flexural strength ...

This paper presents the results of a parametric study on response unreinforced and retrofitted masonry specimens. The adopted strengthening technique is steel-reinforced plaster, which very commonly used but it not supported by proper theoretical experimental characterization in scientific literature. aim was to investigate main parameters that affect structural performances walls. Several nume...

The paper provides mathematical modelling for prefabricated timber-framed walls composed of a timber frame and two different types of sheathing boards. Since by wood-based boards (WBB) the tensile strength is similar to the compressive one, there are practically no cracks appearing in the boards. On the other hand, in case of fibre-plaster sheathing boards (FPB) the tensile strength is approxim...

Short banana fiber reinforced composites have been prepared in laboratory to determine mechanical properties. It has been observed that as soon as the percentage of the banana fiber increases slightly there is a tremendous increase in ultimate tensile strength, % of strain and young modulus of elasticity. Reinforcement of banana fibers in epoxy resin increases stiffness and decreases damping pr...
