Introduction

Hollowcore Load Manager is tool purpose-built tool to define hollowcore loads. Use the tool to easily create slab loads, area loads, line loads and point loads. Loads are automatically recognized as input loads in the hollowcore calculation of Hollowcore integration extension.

Start

To use the entire extension package meant for hollowcore calculations, install also extensions "Hollowcore integration" and "CADeON SA" from Tekla Warehouse.

Hollowcore Load Manager contains one main tool called “Hollowcore Load Manager” and four sub-component for each load type. With the main tool “Hollowcore Load Manager” it’s possible to create the different sub-components from the same user interface. Once loads are created, the loads are created as the sub-component instance.

Dialog

Tab pages in the “Hollowcore Load Manager” are

Slab load
Area load
Line load
Point load

Slab load

Name	Name of the load. Used only for the user to differentiate the different loads.
Load	Value of the area load in the entire slab.
Type	Load type.
Create two slab loads	Set to “Yes” to create two different slab loads.

There are two methods to create slab loads:

Create

Select the object that will get slab loads

Create to selected

Select object(s) or component
Press "Create to selected"

Area load

Name	Name of the load. Used only for the user to differentiate the different loads.
Load	Value of the area load at the start and at the end of the area load.
Type	Load type.

Creation:

Select the object or component to set the plane of the load
Pick the first corner of the rectangular area load
Pick the opposite corner of the rectangular area load

Line load

Name	Name of the load. Used only for the user to differentiate the different loads.
Load	Value of the line load at the start and at the end of the line load.
Type	Load type.
Distribution	Distribute the “input load” to multiple slabs. Type the percentage that each slab will get from the “input load”. The slab in the middle is the slab where the line load is created. The total sum of the percentages must be 100%. If there is load distributed to the next slab but there is no slab in the model where to distribute the load into, the load will be returned back to the slab where the line load is created to. Image

Creation:

Select the object or component to set the plane of the load
Pick the start point of the line load
Pick the end point of the line load

Point load

Name	Name of the load. Used only for the user to differentiate the different loads.
Load	Value of the point load.
Type	Load type.
Distribution	Distribute the “input load” to multiple slabs. Type the percentage that each slab will get from the “input load”. The slab in the middle is the slab where the point load is created. The total sum of the percentages must be 100%. If there is load distributed to the next slab but there is no slab in the model where to distribute the load into, the load will be returned back to the slab where the line load is created to.

Creation:

Select the object or component to set the plane of the load
Pick the location of the point load

Load definitions

Load types and safety factors are taken from the Options. Go to file menu -> Options -> Load modeling -> Eurocode tab page to adjust the safety factors.

Please check the instructions of the calculation provider, in order to understand how the safety factors are used in the calculations and how load combinations are supposed to be handled.

TIP: You can adjust the scaling of the load objects in the model to make the loads easier to see and separate from each other by adjusting the sizes and scale in "Arrow length" tab page.
