Abstract
In order to promote the efficient use of composite materials in civil engineering infrastructure, effort is being directed at the development of design criteria for composite structures.
The composite structures used in civil engineering are usually defined as structures consisting of sub elements of different engineering materials [3].

Keywords: pulp fibres, swelling, absorptivity, lightweight composites.
This phenomenon, which is considered as negative from the point of view of pulp fibres utilizing for paper manufacturing, could potentially find its positive application in other areas, e.g. in the civil engineering for production of lightweight composites, where the reduction of water absorption of natural fibre materials is desirable.
While the effect of swelling and absorptivity of pulp used to make paper is desirable, for use in other areas, e.g. in the civil engineering for production of lightweight composites, these phenomena are undesirable.
However, in the civil engineering in production of lightweight composites, wherein the vegetable fibres (also tested hemp hurds - HH) are used as filler, the fibres are treated to reduce the absorptivity.
In the civil engineering in production of lightweight composites, wherein this vegetable fibres (in recent times hemp hurds, too) are used as filler, the fibres are chemically or physically treated to reduce absorptivity.

And all of methods need complicated programs for calculation which restrains the theory of reliability in civil engineering application [1-3].
Therefore, this paper is to improve calculating efficiency for most of engineers and to push forward the application of Matlab in structural reliability engineering.
Optimization Algorithm of Reliability Indexes The second moment reliability index as defined by Hasofer and Lind (1974) is generally considered to be a better approach in civil engineering design than the conventional factor of safety concept.
In engineering, many random variables do not follow normal distribution.
