This paper presents the results of a study on the out-of-plane seismic behavior of confined masonry walls. The former was determined using the unidirectional strut method and the latter using a plastic analysis. Analytical strengths of confined walls are determined using this method. Simulation more...

I think it is probably good practice in most cases to have the beam or joist bear on something rather that have it nailed in, but is it required? Gothic architecture allowed structures to maintain an open interior space, transferring more weight to the buttresses instead of to central bearing walls. more...

This chapter does not apply to the alteration of existing electrical, plumbing, mechanical or fire safety systems. In structural engineering, most problems can be modeled with one-dimensional line elements, or two-dimensional plate or shell elements, and result in reasonably accurate solutions. Make more...

The calculation also checks the stability of the wall for mainly vertical loading, at the half height beneath the concentrated load. Users of this program must determine the validity of the results. The calculation checks the localized bearing resistance of the masonry directly beneath the load more...

The opening will be about 6′ wide and 3′ high. My question is what size steel to put in. This post is not going to help you with the calculations to arrive at what loads you need the lintel to bear – that is for another blog post.The weight of the lintel in kg per metre. The second method in more...

As the calendar (and cyclic events) has always been an essential part of organized religion, this division into 7s was something that religious authors felt the need to explain in cosmic and supernatural terms and such lunar symbology formed a key part of pagan lore.

It is necessary for the pore size of the brick material to be greater than 0.05 mm for a mechanical bond to be formed, and also for the cement to be properly hydrated behind the ettringite layer, despite the withdrawal of some of the water by suction from the brick.

This part cuts a splitting line around the stone or brickwork. Often this is not the case with less expensive tools. It is important that the line is kept free of knots and clean of mortar.

The use of materials such as bricks and stones can increase the thermal mass of a building. Masonry is very heat resistant and thus provides good fire protection. Masonry walls are more resistant to projectiles, such as debris from hurricanes or tornados. The results show soil-structure interactio more...
