3. Modeling A#
3.1. Characteristics of modeling#
Characteristics of the bay:
\(A=2.24E–3{m}^{2}\); \({I}_{y}={I}_{z}=3.7E–6{m}^{4}\); \({J}_{x}=7.4E–6{m}^{4}\); \({A}_{y}={A}_{z}=1.2\)
Characteristics of the posts:
\(A=3.14E–2{m}^{2}\); \({I}_{y}={I}_{z}=4.5E–5{m}^{4}\); \({J}_{x}=9.0E–5{m}^{4}\); \({A}_{y}={A}_{z}=1.2\)
The analysis focuses on \(0.5s\) in 100 equal steps of time.
3.2. Characteristics of the mesh#
The span is modelled by 12 beam elements; each column by 2 elements. All of these elements are \(\mathrm{1m}\) in length.
3.3. Tested sizes and results#
