Abstract.
In the case of the "green" composites, natural fibers derived from bamboo [1], hemp [2], or flax [3] are being added to biodegradable resins to reinforce polymer matrix materials and improve the mechanical properties of resulting composites.
Experimental methods Materials A starch-based, dispersion-type biodegradable polymer (CP-300, Miyoshi Oil & Fat Co., Ltd.) was used as a matrix resin.

The seismic damage feature of multi-story masonry building
Multi-story masonry building belongs to early developed structure, according to its operating principle and material features, and summarize several violent earthquake disaster to conclude that wall is the main load-bearing and later-force-resisting member,its stress shows complex and materials are fragile, so that the earthquake resistant behavior is lower than others relatively.
Using sectional wall to bear load, the material of wall is KP Porous brick, MU10,and the strength grade of mortar is M5 in the 1-st and 2-nd floor, M2.5 for other floor.

This kind of buildings adapting better to locale climate, in a certain sense, it is sustainable, but should be improved with new idea of design and modern technology and material.
2.2 Design strategies for the hot-humid climate
(1) The factors of influencing layout
The precise activities to be housed in any specific building, ranging from an assembly line in a factory to a living room in a home, should dictate the size and shape of the several areas within.
Today, we should extent this way to wider range, which includes: ·Roofing planting, adopting light material planting green ·Wall planting ·Planting on projecting eaves ·Planting on sunshine boards ·Window sill planting ·Balcony planting ·Canopy planting(free drainage benefiting apron planting) ·Apron planting ·Adopt taller seasonal green plants on the South and West (4) Greening design strategies ·buffer layer strategy, for instance, hot buffer atrium, solar shade wall and cascade of slope roofs, solar shade shutter. system; ·natural energy using system, for example, using solar energy(solar housing ,solar cell etc ),using underground water(using it as natural cool and hot source) ·health and harmlessness strategy, for instance, natural ventilate ,greening from outdoors to indoors, harmless material and so on.
But it should be improved with new idea of design and modern technology and material.

It is relatively small to consider effect on and for Poisson ratio, but such an approach does not meet the parameters of the actual geotechnical materials.
Because as rock material changes, its angle of internal friction is bound to change.
