Actuated Truss

This app and video tutorials show how to use actuator-type elements to control the shape of truss-like structures.

Grid Shell

This app and video tutorial introduce “hanging chain” and “active bending” form finding to design grid shell structures. Check out the digital and physical models of grid shell structures designed and built using PushMePullMe 3D at the Berlin University of

Tensegrity

This app models a class-1 type tensegrity structure. The video tutorial shows how prestress cable elements to find an equilibrium state.

Cable Net

This app and video tutorial shows how to apply pre-stress to cable elements in order to form-find cable net structures.

Space Frame

This app models a space frame for a multi-storey building. The video tutorial shows how to use the GUI to apply multiple loads and provide an example of incremental loading up to failure.

PortalFrame vs Arch

This app shows the difference between the structural behaviour of a portal frame with respect to that of a catenary arch. The video tutorial introduces a first example for hanging chain simulation in order to form find catenary arches.

Portal Frame

Simple portal Frame model. Check the demo movie to start using PushMePullMe 3D

Beam 6DOF and Support Conditions

This app and related video tutorials introduces various features of PushMePullMe 3D including drag and drop to apply point loads and UDL loads and assignment of roller-type supports. The video tutorials provide an example of structural failure under large displacement and

Latest Push Me Pull Me

Two Span Simple Beam Continuous Over Central Support with Internal Pin

The section of the beam to the right of the pin experiences no moment, shear, movement or axial force for a substantial range of loadings. Use this Push Me Pull Me app to see how.

Two Span Simple Beam Continuous Over Central Support

The central support reduces the effective span of the beam which results in lower stresses and moments. Use this Push Me Pull Me app to see how

Twin Base Frame with Pinned Bases on Horizontal Rollers

Vertical forces change the distance between the rollers. Use this Push Me Pull Me app to see how.

Three Element Moment Connection

The moment connection ensures that the angle of the intersecting beams remains constant. Use this Push Me Pull Me app to see how.

Simply Supported Beam

A simply supported beam is supported by either a roller or a pin at each end and the load is distributed in some way along its length. Use this Push Me Pull Me app to see how.

Portal Frame with One Fixed Base

The roller can only resist horizontal movement resulting in a large moment in the fixed connection when vertical forces are applied. Use this Push Me Pull Me app to see how.

Pinned Base Portal Frame with Internal Pin

The internal pin is the point of zero bending moment and high shear in the horizontal beam. Use this Push Me Pull Me app to see how.

Pinned Base Portal Frame with Horizontal Roller

Horizontal forces are resisted by the fixed connection. As a result, a heavy duty connection may be required if there is the possibility of high wind loads. Use this Push Me Pull Me app to see how.

Pinned Base Portal Frame

The pinned base allows rotation at the connection and fixed connections ensure the structures stability. Use this Push Me Pull Me app to see how.

Fully Fixed Portal Frame

Fully fixed portal frames result in large bending moments at all connections. Use this Push Me Pull Me app to see how

Diagonally Braced Frame with Pinned Bases

The cross brace in this structure resists lateral loading through either compression or tension depending on the direction of the lateral force. Use this Push Me Pull Me app to see how.

Cross Braced Frame with Pinned Braces

The cross brace in this arrangement resists lateral loading resulting in the ability to use pinned connections throughout the structure. Use this Push Me Pull Me app to see how.

Simply Supported Beam with Cantilever

The cantilever is supported by a roller which resists vertical movement but not horizontal movement. Use this Push Me Pull Me app to see how.

Pinned Base Portal with Rafter Cantilever

Portal frames transfer lateral loads through strong fixed connections at the top of the structure. Use this Push Me Pull Me app to see how.

Pinned Base Portal Frame with Eaves Pin

The pinned base allows small rotation which reduces the size of members required. Use this Push Me Pull Me app to see how.

Encastre Beam

An encastre beam is a horizontal beam which is secured by fixed or non-rotating connections at both ends. Use this Push Me Pull Me app to see how

Cantilever Beam with Single Crank

Cantilever beams with a single crank (angle) are regularly used in supporting signage or advertisements on structures. Use this Push Me Pull Me app to see how.

Cantilever Beam with Double Crank

Crank is a term used to describe a bend or angle in a beam. This cantilever has two and the resulting lever arm creates additional bending moments in the fixed connection. Use this Push Me Pull Me app to see

Cantilever Beam

A cantilever is a beam that is anchored at only one end. Cantilever construction allows for overhanging structures without external bracing. Cantilevers can also be constructed with trusses or slabs. Use this Push Me Pull Me app to see how

Simple Warren Truss

A warren truss consists of longitudinal members joined only by angled cross members. The equilateral shaped design ensures stability and ease of design due to the resulting lack of bending forces in the members. Use this Push Me Pull Me
