Abstract This paper presents preliminary results from research on developing a statistical human body model for use in calculating jump effects on scaffold boards. This work, which takes forward the work of a previous research programme, is aimed at using available measurements to predict jump effects under conditions not considered previously. Keywords: Human body model, jump effects, scaffold boards, structural dynamics

1 Introduction

Scaffold boards, which form part of temporary access platforms, are commonly subject to forces that result from human jumps. In order to obtain information on these impact forces, through the sponsorship of the Health and Safety Executive, BRE have conducted an investigation aimed at quantifying such forces. The results of earlier work were published in two previous papers by Canisius eta/. [1] [2]. The work reported in this paper is aimed at using the available measurements to predict jump dynamic effects under conditions not considered previously.
