Description

  The present invention relates to a foundation / ground reinforcement design program for small-scale buildings.

Many programs related to architecture have been used in the past, but most of them are partial, and there were no programs that could output the final drawing of the foundation by inputting the basic data.

In order to solve the problems as described above, a foundation / ground reinforcement design program for a small-scale building of the present invention includes a step of inputting a ground constant and building specification data, a step of determining the feasibility of a direct foundation, When it is judged that the foundation is directly established, all of the multiple ground reinforcement methods when it is judged that the foundation slab section calculation of the fabric foundation or the solid foundation and the section calculation of the foundation beam and the foundation foundation are not established. Alternatively, a part is selected to calculate a design value of the local reinforcement method and a step of outputting a calculation result from the input data as a structural calculation document.

Since the foundation / ground reinforcement design program for small-scale buildings of the present invention is configured as described above, it is only necessary to input the ground information and the basic data of the planned building, and the final drawing of the foundation and the structural calculation sheet can be quickly completed. Can achieve the effect of being able to output with

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

<1> Ground data input.
Investigate the ground where the building will be built.
The ground survey includes, for example, a Swedish sounding test, a standard penetration test, a cone penetration test, and a soil survey.
The numerical value of the ground survey result is input to the program of the present invention.

<2> Input of building data.
Enter the data for the building you plan to build.
For example, building area, total floor area, number of floors, floor plan, node coordinates, and the like.
Moreover, the load condition which acts on a foundation is input.
The load conditions include a roof load, a floor wall load on each floor, and the like.

<3> Creation of ground model.
From the ground survey results performed in the previous step, determine the soil type, thickness of each layer, groundwater level, and ground constant of each layer.
At that time, whether the stratum is a stratified ground or a sloping ground is also a consideration condition.
For example, the soil type is classified into sand, cohesive soil, humus soil, gravel, and embankment.

<4> Examination of feasibility of direct foundation.
The allowable vertical bearing force is calculated from the above values.
As a result, the foundation load is compared with the allowable supporting force to determine the foundation of the foundation directly.
Also calculate the amount of settlement.
From the result, the subsidence amount of the foundation and the allowable subsidence amount are compared, and the feasibility of the foundation is directly determined.
Thus, a case where the foundation is directly established and a case where the foundation is not established are calculated, and the subsequent steps are divided into a case where the foundation is established and a case where it is not established.

<5> Basic calculation.
When it is determined that the foundation is directly established, the foundation slab section calculation and foundation beam section calculation of the cloth foundation or solid foundation are performed.
As a result, the thickness, dimensions, reinforcing bar amount, bar arrangement state, etc. of the foundation slab and foundation beam are calculated.

<6> Output of calculation results.
The above calculation results are output as numerical values and further output as a drawing.
These documents will adopt a layout that can be used as is as a calculation statement submitted to the owner or government office.
Save the output data.

<7> Design of ground reinforcement method.
If it is determined that the foundation is not directly established, it is necessary to construct a ground reinforcement method for reinforcing the ground.
As the ground reinforcement construction method, a construction method for placing a small-diameter pile, a construction method for improving the ground in a columnar shape, a construction method for improving the ground of the surface layer, or a RES-P construction method can be employed.
For the design of small-diameter piles, the vertical bearing capacity, horizontal bearing capacity, and settlement amount of the pile are calculated, and the diameter, material, length, and installation interval of the pile to satisfy the required performance are calculated.
In this way, a plurality of ground reinforcement methods are selected, and the design values of the local reinforcement methods are calculated.
After that, by comparing economic efficiency and other conditions, the optimum ground reinforcement method at the site is selected from a plurality of methods.
Then, various numerical values of the selected construction method and the drawings are output as a structural calculation sheet to complete the work.
Therefore, the output product can be submitted to the orderer or the government office as it is, and it can be said that it is extremely convenient for the designer.
