Static Detail Description
Tower with Bridge – Vertical–Horizontal Composite Structure (Model_F)
1. Model Description
The Tower with Bridge model consists of a vertical tower structure built from stacked cubic base modules, combined with a horizontally projecting and/or connecting bridge element at an upper level.
The purpose of the model is to examine the interaction between vertical load transfer (tower) and horizontal extension (bridge) within a modular system, without assuming any use by persons.
2. Geometry and Assembly
-
Base elements: cubic modules, 1.0 × 1.0 × 1.0 m
-
Tower: vertical stacking of multiple cubes
-
Bridge: horizontally oriented module, connected laterally to the tower
-
Modularity: identical profiles and node logic as in the other OSM models
All members are made of aluminium square hollow sections 25 × 25 × 2.0 mm (EN AW-6060 T6).
3. Nodes and Connections
-
Cartesian Rietveld Nodes
-
Bolted connections
-
M6 bolts (steel S235)
-
Ø 6.5 mm drilled holes with steel washers
The connections are:
-
not moment-resisting
-
to be understood as semi-rigid joints
Overall stability is generated by the global geometry, not by individual joints.
4. Supports / Bearings
-
Point supports at the base of the tower
-
no horizontal fixity assumed
-
no additional bracing of the bridge assumed
The bridge is not supported separately; it is entirely carried by the tower.
5. Load Assumptions
The model is not intended for use by persons.
Applied loads:
-
self-weight of the tower
-
self-weight of the bridge
Not applied:
-
live loads
-
horizontal loads from leaning or walking
-
dynamic or traffic-related loads
The static evaluation is limited to self-weight and constructive stability.
6. Structural Behaviour
The load-bearing behaviour is hierarchically organised:
Tower (vertical)
-
acts as the primary structural system
-
carries:
-
self-weight of all stacked modules above
-
self-weight of the bridge
-
-
internal forces mainly:
-
axial forces
-
minor bending moments
-
Bridge (horizontal)
-
acts as a secondary element
-
is:
-
non-walkable
-
not independently load-bearing
-
-
induces:
-
local bending moments at the connection zone
-
additional demand on the tower
-
7. Deformation and Stability Behaviour
-
Global stability is governed by the tower
-
The bridge introduces:
-
an eccentric load
-
limited additional deformation
-
-
Given the low load level:
-
deflections remain small
-
no critical tipping or torsional mechanisms are expected
-
The system behaves in a controlled elastic manner.
8. Static Assessment
The combined tower-and-bridge arrangement is structurally plausible under self-weight and for temporary use without person loads.
The construction:
-
provides clear load paths
-
is systemically stable
-
avoids unnecessary over-stiffening
The tower, not the bridge, is the governing component for structural capacity.
9. Limits of Use
Suitable for:
-
spatial markers
-
modular high structures with a horizontal accent
-
temporary, non-interactive installations
Not intended for:
-
walking or sitting on the bridge
-
larger cantilevers without additional bracing
-
permanent structural use
10. System Context
The Tower with Bridge model functions as:
-
an extension of vertical cube-based structures
-
a link between high structures and spatial “reach” elements
-
a reference model for hierarchical structural logic within the OSM system

Statische Detailbeschreibung
Tower with Bridge – Vertical–Horizontal Composite Structure
(Model_F)
1. Modellbeschreibung
Das Modell Tower with Bridge besteht aus einer vertikalen Turmstruktur, die aus gestapelten kubischen Basismodulen aufgebaut ist, sowie einem horizontal auskragenden bzw. verbindenden Brückenelement auf einer oberen Ebene.
Ziel des Modells ist es, das Zusammenspiel vertikaler Lastabtragung (Tower) und horizontaler Ausdehnung (Bridge) innerhalb eines modularen Systems zu untersuchen, ohne eine Nutzung durch Personen vorzusehen.
