摘要: 
本文乃針對營造階段中以木材作為模板支撐,探討木材模板支撐系統之承
載能力。在配合工地實務使用狀況下,進行一系列之承載力試驗。試驗工
作包括木材基本力學性質試驗、木材支撐於垂直架設及傾斜架設,及續接
方式使用其承載能力之影響,並進行多根木材支撐結構系統之壓壞試驗。
試驗所得木材基本力學性質及木材支撐力之實驗數據,經考慮模板載重狀
況及木材支撐之安全因子後,可直接提供作為模板支撐強度之分析設計;
而於木材續接試驗中,發現搭接式木支撐存在相當大之位移量,應以適當
之位移控制其設計之支撐強度。本文另外亦提出一改良式木材支撐之配置
系統,經試驗結果證明,無論在施工便利性及支撐承載能力之整體行為上
,此改良式之配置均優於現行配置方式,實可做為木材模板支撐設計之參
考。

The objective of the studies presented in this thesis is to
investigate the resistant capacity of wooden shores used
for formwork support during construction. To
simulate real construction conditions, a series
of experimental researches were carried out in the
laboratory. It includes tests on basic mechanical
properties of wood, single vertical and inclined wooden
shores with a variety of lengths, lap spliced shores,
and a support system w ith multiple shores. Results
obtained from the tests show that the basic mechanical
properties can provide important information on analysis and
design of wooden shoring supports. The Euler buckling equation
is also suitable for prediction of buckling loads of single
wooden shores of various lengths. The use of lap
spliced shores will cause a large displacement at the
overlapping area, such that the load-carrying capacity
should be controlled by the allowable d isplacement
depending on the formwork requirement. The average load-
carrying capacity of a support system with multiple
shores is less than that of a single wooden shore. Based
on the experimental results, a better and relatively easy
set-up support system is proposed.
