The purpose of this study is to present the evaluation method of contact resistance between hands and building elements from the view point of safety. In this repot, we firstly carried out sensory test, to make the evaluation scales of posture keeping in slipperiness with hands. Next, we developed the slip meter that could measure the slip resistance of plane samples. Then, coefficients of slip resistance of the plane samples by various slider materials, shapes, vertical loads and pull speeds are searched with the slip meter. Also, the relations are investigated between slip resistance and evaluation scales of posture keeping in slipperiness. As a result, we presented main points of measurement method of slip resistance of building elements and members with hands.

This paper deals with est正 mation of the sIrength in high strength concrete structures subjected to high temperaIure history caused by hydration hea10f cement ， The compressive strengths of standard cured spec 孟 mens ， on site seal cured specimens ， and adiabaticaliy cured specimens using the newly deve 正 一 〇 ped simple mcthod were compared w 三 th the strength in structures ． The temperature history of the adiabatical 正 y cured specimens were also compared wiIh the temperature history of structure ． It was fbund that the temperature histoly of the adiabatically cured specimens were similar to that of the structure at ear亘 y age， Is concluded that山 e strength in high s1rength concrete structure can be estimated using the simple adiabatic curing ． 1 ．は じめ に
