Structural engineering
Welcome to XC
Pursuing structural engineering solutions for society.
We strive to contribute to society with structures that fit with the 3 E's of structural art: Efficiency, Economy, and Elegance. Our senses are open to Nature, both for learning from its beautiful forms as for raising personal awareness about sustainability. In terms of technology, we develop, with self-imposed mandate for openness and knowledge-sharing, much of the software that we use; conceiving tools to enhance, rather to compete with, the creative human process of design.

DECXC tutorial 3: Properties of a reinforced concrete section obtained from a fiber-section model.
This tutorial deals with a simple RC rectangular section subjected to uniaxial bending. Two layers of reinforcing bars are placed at the top and bottom faces. By integration over the fibers, we obtain geometrical and mechanical properties of the section as well as its deformation under load.

DECSecond tutorial: Vibrating string under tension
This XC-tutorial deals with a flexible string fixed at the ends and stretched to an initial strain. The aim is to determine the first three natural frequencies of lateral vibration of the stretched string.

OCTFirst tutorial: Getting started with XC
This tutorial deals with a steel bar of uniform cross section whose ends are fixed from translational motion. The goal is to find the axial force in the bar subjected to a uniform temperature increase.

MARTangled up with fibers
These days we are playing with XC fiber-material models of reinforced concrete sections. By integrating different fiber properties, we can find useful quantities relative to the geometry and tensional state of the section.

SEPT.Prestressed concrete slabs in XC
We are implementing in XC some developments to model prestressed concrete slabs.To test these tools, we create a 3D model of bridge with longitudinal and transverse prestressing tendons.

FEBRUARYAnalysis of a building with XC.
We have posted on the blog a case study that deals with a six-storey building with two underground parking levels. The displacements and internal forces are calculated with XC for several load combinations.
