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...
I need at least 1 anchor bolt for each 8′ of wall section. Anchor bolts have to be installed properly for them to be effective. The size and location of structural elements, reinforcement and anchors. The magnitude and location of prestressing forces. Anchorage length of reinforcement and locat 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...
However, you might have never heard about wet saws for cutting stone, or even be able to conceptualize how a wet saw might work. If you’ve ever walked through the city while workers were doing street repairs with a jackhammer, then you have an idea of how much dust can get kicked up when cutting t 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.

Indian proverb explains; “the arch never sleeps”. I laid a series of stone arches below the wood-framed terrace of a new residence. The overhead pressure is redistributed to the ring stones and down to the springer stone at the base of the arch. Damage and collapses caused by earthquakes sh more...
The slenderness ratio, in turn, depends upon the effective height (or length) and the effective thickness of the wall or column. This video talks about the constituents of the concrete,. It explains the meaning of characteristic strength and target mean strength…Verifying Compressive Strength more...
Could be used as well for play box sand. and it doesn’t stop there, we can also work with you to get pricing and materials for large jobs needing thousands of yards of materials. All right, but how much does a yard of sand weigh? Once you know the total weigh of sand you have to buy, you won’t more...
It is often appropriate to analyze some stories using the rigid diaphragm assumption and other stories using the semi-rigid assumption. Hidden surfaces are represented by short dashed lines. www.youtube.com/watch?v=dHx_pohtObU Deflection Analysis of High Performance Exterior Wall Systems – more...

Iran during the last 40 years of the 20th century. All specimens were tested under constant gravity load and incrementally increasing in-plane loading cycles. In seismic oscillation, the instantaneous dynamic displacements of multiple positions on masonry walls can warn of crack development and more...
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. Shear Strength Criteria and Re more...
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. Masonry tools I use, (Part 1) Levels, trowels, and hammers, and some information on where I buy, below more...
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...
The micro-mechanical model can be implemented in any standard finite element program as a user supplied subroutine defining the mechanical behaviour of an equivalent homogenised material. The aim of the research is to implement and validate a reliable and fast numerical tool able to represent th more...
To ensure that such a façade remains durable over the long term, the dead load of the outer skin of brick must be transferred to the building structure. Different brackets are available which permit either assembly on the top or on the edge of concrete slabs. Installation remains simple and flex more...

This leaves me with the need to update my lintel schedule on the job. Masonry veneers can also be attached to poured concrete walls. The slab edge is then supported by a spandrel beam.
